Work Step by Step

RECALL: $g(a)$ represents the value of the function $g$ when $x=a$. To find the value of $g(10)$, look for the point on the graph where $x=10$. Notice that from $x=2$ to the right, the function $g$ is represented by the horizontal line $y=-2$. This means that the value of the function $g$ in the interval $[2, \infty)$ is $-2$. Thus, $g(10)=-2$.
