Math Problem Statement
Question
Consider the graph of
f
′
(
x
)
below. How many local maxima does
f
(
x
)
have?
A curve on a coordinate plane.
A coordinate plane has a horizontal x-axis labeled from negative 5 to 5 in increments of 1 and a vertical y-axis labeled from negative 4 to 4 in increments of 1. From left to right, a curve labeled f prime rises in quadrant 3 to a local maximum at left-parenthesis negative 2 comma 0 right-parenthesis, falls to a local minimum at left-parenthesis negative 1.5 comma negative 3.2 right-parenthesis, rises to a local maximum at left-parenthesis 0 comma 0 right-parenthesis, and falls to left-parenthesis 0.8 comma negative 0.4 right-parenthesis, and then rises passing through left-parenthesis 1 comma 0 right-parenthesis. All coordinates are approximate.
