Explanation:

Step1: Locate x = -2 on x - axis

Find the position of \( x=-2 \) on the horizontal (x - axis) of the graph.

Step2: Find corresponding y - value

From \( x = - 2\), move vertically until intersecting the graph of \( y = f(x) \). The y - coordinate at this intersection point is the value of \( f(-2) \). By observing the graph, when \( x=-2 \), the y - value is \( - 6 \).

Answer:

\(-6\)
