find the value of f(-6). y = f(x)

Explanation:

Step1: Locate x - value on graph

Locate $x=-6$ on the x - axis.

Step2: Find corresponding y - value

Find the point on the graph where $x = - 6$. The y - value of this point is the value of $f(-6)$. Looking at the graph, when $x=-6$, $y = - 2$.

Answer:

$-2$
