Question

Use the graph of f to estimate the local maximum and local minimum.
A piecewise graph is shown with a line increasing to 0,-2 terminating at that point and a curve starting at 0,0 and intercepting the x axis at 0, pi, and 2pi.


help me please no good in graph

Answer 1

Unfortunately, the statement is a bit confusing, because the graph of curve is not clear. Maybe you meant a sine function.
