Answer
absolute maximum $f(3)=4$, absolute minimum $f(1)=1$, local maximum $f(3)=4$, local minimum $f(1)=1$.
Work Step by Step
Based on the given graph, we can find the absolute maximum $f(3)=4$ and the absolute minimum $f(1)=1$, we can also identify the local maximum $f(3)=4$ and the local minimum $f(1)=1$.
