The function f(x) is graphed below. How many points on the graph represent a relative maximum?

To determine the number of points on the graph that represent a relative maximum, we need to identify the points where the graph changes from increasing to decreasing.

In the given graph, there are two points where the graph changes from increasing to decreasing. These points are the highest points on each side of the graph. Therefore, there are 2 points on the graph that represent a relative maximum.
