Question Use graphing technology to find the range of the function f(x)=-x^2 Answer Attemptiontof?

To find the range of the function $f(x)=-x^{2}$, we can use graphing technology.<br /><br />Step 1: Plot the function $f(x)=-x^{2}$ on a graph.<br /><br />Step 2: Analyze the graph to determine the range of the function.<br /><br />The graph of the function $f(x)=-x^{2}$ is a downward-opening parabola. The vertex of the parabola is at the point (0, 0), and the parabola extends infinitely downward.<br /><br />Therefore, the range of the function $f(x)=-x^{2}$ is $(-\infty, 0]$.<br /><br />Answer: The range of the function $f(x)=-x^{2}$ is $(-\infty, 0]$.
