The graph of a polynomial function is given. 1x3+3 P(x) =- 2 x 1 2 6 4 2 x -6 -4 -2 2 4 6 2 41 6 (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) = y-intercept (x, y) = (larger x-value) (b) Find the coordinates of all local extrema. (If an answer does not exist, enter DNE.) local minimum (x, y) = local maximum (x, y) =
