To graph the function \( f(x) = -\frac{1}{4} x^{2} \), start by noting that this is a downward-opening parabola with its vertex at the origin (0,0). The negative coefficient indicates that it opens downwards, making it an upside-down "U" shape. You can plot a few key points: at \( x = -4, f(-4) = -4 \), at \( x = -2, f(-2) = -1 \), at \( x = 2, f(2) = -1 \), and at \( x = 4, f(4) = -4 \). Connecting these points will form your parabola! When graphing, you’ll notice that the parabola gets wider as you move away from the vertex. This is due to the fractional coefficient \(-\frac{1}{4}\), which makes the parabola less steep compared to one with a larger coefficient. You might want to explore how changing the coefficient affects the "width" of the parabola!
