Question

evaluate the function graphically.
find ( f(-3) )

Explanation:

Step1: Understand the function value concept

To find \( f(-3) \), we look at the \( y - \)value of the function when \( x=-3 \). A closed - dot on a graph represents the actual value of the function at that \( x - \)coordinate, while an open - dot means the function is not defined at that point (in the context of the continuous part of the line).

Step2: Locate \( x = - 3 \) on the graph

On the given graph, when \( x=-3 \), we observe the closed - dot. The \( y - \)coordinate of the closed - dot at \( x = - 3 \) is used to determine \( f(-3) \).
