#### Answer

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

#### Work Step by Step

The arrowhead on the left side rises to the left. This means that the function covers all the negative x-values from $-3$ to the left.
The arrowhead on the right side rises to the right. This means that the function covers all the real numbers from $-3$ to the right.
The graph covers all possible x-values therefore its domain is $-(-\infty, +\infty)$.
The graph of the function covers all the y-values from $0$ and above.
Thus, its range is $[0, +\infty)$.
