evaluate the function graphically. find f(-4)

Explanation:

Step1: Locate x - value on x - axis

Locate $x=-4$ on the x - axis.

Step2: Find corresponding y - value

For the function graph, when $x = - 4$, the open - circle at $(-4,1)$ means the function is not defined at this point. But looking at the part of the graph approaching $x=-4$ from the left, the y - value corresponding to $x=-4$ for the continuous part of the graph is $y = 1$.

Answer:

$1$
