Ill mark brainliest 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.
local maximum: (0,-2); local minimum: (0,0) and (π,0)
local maximum: pi over two, 1; local minimum: three pi over two, negative1
local maximum: (0,0) and pi over two, 1; local minimum: (0,0) and three pi over two, negative 1
local maximum: (0,0) and pi over two, 1; local minimum: three pi over two, negative 1
