Complete The Table: Y = (1/4)x^2 Values

Hey guys! Today, we're diving into a super fun math problem that involves completing a table for a quadratic equation. Don't worry, it's not as scary as it sounds! We'll be working with the equation y = (1/4)x^2, and our mission is to find the corresponding y values for the given x values: -6, -4, -2, 0, and 2. Think of it as a puzzle where we plug in the x values and solve for y. Ready to jump in and make some mathematical magic happen? Let's get started!

Understanding the Equation

Before we start plugging in numbers, let’s break down the equation y = (1/4)x^2. This is a quadratic equation, which basically means it will create a U-shaped curve, also known as a parabola, when we graph it. The x^2 part is the key here – it tells us that the y values will change in a non-linear way as x changes. The (1/4) in front of the x^2 acts as a scaling factor, making the parabola wider than the basic y = x^2 graph. So, understanding this fundamental equation is the first step in solving our problem. When we square a number, we multiply it by itself. For example, 2 squared (2^2) is 2 * 2 = 4. Negative numbers also become positive when squared because a negative times a negative is a positive. For instance, (-2)^2 is (-2) * (-2) = 4. This squaring action is crucial because it affects how the parabola curves. After we square x, we multiply the result by (1/4). This step is like taking a quarter of the squared value. It shrinks the y values compared to if we were just looking at y = x^2, making the parabola broader. Knowing this, we can predict how the y-values will behave. They'll grow as x moves away from zero, but more slowly because of the (1/4) factor. Also, because of the squaring, we'll get the same y value for both positive and negative versions of the same x number (like -2 and 2). This symmetry is a hallmark of quadratic equations and helps us anticipate our results. So, with this basic understanding, we’re well-equipped to tackle filling in the table and seeing this mathematical concept come to life!

Calculating the Values

Okay, let’s get our hands dirty and calculate the y values for each given x value. This is where the fun really begins! We’ll take each x value, plug it into the equation y = (1/4)x^2, and then carefully solve for y. We'll go through each step, so you can follow along and see exactly how it's done. First up, let’s tackle x = -6. We substitute -6 into our equation: y = (1/4)(-6)^2. Remember, the order of operations is super important here. We need to square -6 first. So, (-6)^2 is (-6) * (-6), which equals 36. Now our equation looks like this: y = (1/4) * 36. To finish it off, we need to find one-fourth of 36. You can think of this as dividing 36 by 4, which gives us 9. So, when x = -6, y = 9. See, not too bad, right? Let's move on to our next value, x = -4. We're going to follow the same steps: y = (1/4)(-4)^2. First, square -4: (-4)^2 = (-4) * (-4) = 16. Then, multiply by (1/4): y = (1/4) * 16. One-fourth of 16 is the same as 16 divided by 4, which is 4. So, when x = -4, y = 4. We're on a roll! Next, let's plug in x = -2: y = (1/4)(-2)^2. Square -2: (-2)^2 = (-2) * (-2) = 4. Now, multiply by (1/4): y = (1/4) * 4. One-fourth of 4 is 1, so when x = -2, y = 1. We're halfway there! Now let's consider x = 0. This one's a bit special: y = (1/4)(0)^2. Zero squared is just 0, so we have y = (1/4) * 0. Anything multiplied by 0 is 0, so when x = 0, y = 0. Last but not least, let's do x = 2: y = (1/4)(2)^2. Square 2: (2)^2 = 2 * 2 = 4. Then multiply by (1/4): y = (1/4) * 4. One-fourth of 4 is 1, so when x = 2, y = 1. And there you have it! We've carefully calculated all the y values for each given x value. Now, let’s put them all together in our table.

Filling the Table

Alright, we've done all the hard work calculating the y values. Now comes the satisfying part: filling them into our table! This is where we organize our results in a neat and easy-to-read format. Our table will have two columns: one for the x values and one for the corresponding y values we just computed. Remember, the table is a visual representation of the relationship between x and y for the equation y = (1/4)x^2. When we fill in the table, we're creating a set of ordered pairs (x, y) that we could plot on a graph to see the shape of the parabola. So, let’s take each x value and its matching y value and slot them into the right place in our table. Starting with x = -6, we found that y = 9. So, we'll put 9 in the y column next to -6 in the x column. This gives us our first ordered pair: (-6, 9). Next up is x = -4, where we calculated y = 4. We'll write 4 in the y column beside -4 in the x column. Our second ordered pair is (-4, 4). For x = -2, we found that y = 1. So, we’ll enter 1 in the y column next to -2 in the x column, giving us the ordered pair (-2, 1). Now for x = 0, we got y = 0. This one's easy! We put 0 in the y column beside 0 in the x column, resulting in the ordered pair (0, 0). Lastly, for x = 2, we calculated y = 1. We write 1 in the y column next to 2 in the x column, giving us the ordered pair (2, 1). And just like that, we've populated our entire table! We now have a complete set of x and y values that describe the behavior of the equation y = (1/4)x^2 for the given x values. Take a moment to admire your handiwork – you've successfully transformed an equation into a set of coordinates. To give you a clear picture, here’s what the completed table looks like:

Isn't it awesome to see all the pieces come together? This table not only shows us the y values for specific x values, but it also gives us a sneak peek into the symmetry and shape of the parabola that this equation represents.

Graphing the Points (Optional)

Now that we've filled in our table, we've got a fantastic set of data points just begging to be visualized! If you're feeling extra adventurous, the next step is to plot these points on a graph. Trust me, it's like watching the equation come to life! Graphing the points helps us see the bigger picture and understand the shape of the curve that our equation represents. We can use the table values as coordinates to plot the points on a graph. Each (x, y) pair from our table becomes a point on the coordinate plane. So, let’s recap our ordered pairs from the filled table. We have (-6, 9), (-4, 4), (-2, 1), (0, 0), and (2, 1). These are our key points for plotting. To start graphing, you'll need a coordinate plane. This is just a grid with two axes: the horizontal x-axis and the vertical y-axis. The point where they intersect is the origin (0, 0). Now, for each ordered pair, we'll find the x value on the x-axis and the y value on the y-axis, and mark a point where they meet. For example, to plot (-6, 9), we find -6 on the x-axis and 9 on the y-axis, and put a dot where those lines intersect. We repeat this for all our points. Once you've plotted all the points, you should start to see a pattern emerge. If you connect the dots with a smooth curve, you'll see the characteristic U-shape of a parabola. This curve is the visual representation of the equation y = (1/4)x^2. You’ll notice that the parabola opens upwards and is symmetric around the y-axis. The lowest point of the parabola, called the vertex, is at the point (0, 0), which we also plotted from our table. Graphing is an awesome way to solidify your understanding of equations and how they translate into shapes. Plus, it's super satisfying to see the curve form as you plot each point. So, if you have the chance, grab some graph paper or use an online graphing tool and give it a try. You'll gain an even deeper appreciation for the math we’ve been doing!
