#### Answer

$E$
domain: $(-\infty, +\infty)$
range: $[0, \infty)$

#### Work Step by Step

The graph of the squaring function $f(x)=x^2$ is a parabola (U-shaped) that opens upward (refer to page 250 of the textbook).
Thus, the graph of $f(x)=x^2$ is the one in Option E.
The graph covers all x-values so the domain is $(-\infty, +\infty)$.
The graph covers the y-values from $0$ and above so the range is $[0, \infty)$.
