The graph and equation of the function f are given.
a. Use the graph to find any values at which f has a
relative maximum, and use the equation to calculate the
relative maximum for each value.
b. Use the graph to find any values at which f has a
relative minimum, and use the equation to calculate the
relative minimum for each value.
