(B). Find the coordinates of all local extrema

The graph of a polynomial function is given. P (x) = 4x3 - 2x2 6 4 2 -6 - 4 -2 X 2 4 6 - 21 -4 (a) From the graph, find the x- and y-Intercepts. (If an answer does not exist, enter DNE.) x-intercepts (x, y ) = ( (smaller x-value) ( x, y ) = ( (larger x-value) y-intercept ( x , y ) = (
