Answer
absolute minimum $f(0)=0$; no absolute maximum
local maximum $f(2)=3$, local minima $f(0)=0$, $f(3)=2$..
Work Step by Step
Step 1. Based on the given graph, we can find only the absolute minimum $f(0)=0$.
Step 2. Based on the given graph, we can find the local maximum $f(2)=3$, local minima $f(0)=0$, $f(3)=2$..
