evaluate the function graphically. find f(-8)

Explanation:

Step1: Locate x - value on x - axis

Locate $x=-8$ on the x - axis.

Step2: Find corresponding y - value

There is no point on the graph corresponding to $x = - 8$. So, we assume the function is not defined at $x=-8$.

Answer:

The function $f(x)$ is not defined at $x = - 8$.
