Answer
absolute maximum $f(2)=4$, absolute minimum $none$, local maximum $f(2)=4$, local minimum $f(0)=2$.
Work Step by Step
Based on the given graph, we can find the absolute maximum $f(2)=4$ and the absolute minimum $none$, we can also identify the local maximum $f(2)=4$ and the local minimum $f(0)=2$.
