Answer: -2
=====================================================
Explanation:
Check out the diagram below.
Draw a vertical line through 2 on the x axis.
This vertical line crosses the blue graph at some point, we'll call this point P.
Draw a horizontal line from point P to the y axis. You should arrive at y = -2
The input x = 2 leads to the output y = -2. The point (x,y) = (2,-2) is on the graph.
This means f(2) = -2.
