Solution Steps

Step 1: Identify the function f(x) on the graph

Examine the left graph to identify the function f(x). The function is represented by the blue points and lines.

Step 2: Locate the y-value of -5 on the graph

Find the y-value of -5 on the y-axis of the left graph. This is the horizontal line where we need to find the corresponding x-values.

Step 3: Determine the x-values where f(x) = -5

Trace horizontally from the y-value of -5 to the points where it intersects the graph of f(x). Identify the x-values at these intersection points.

Final Answer

The x-values where f(x) = -5 are x = -7 and x = 7.
