Consider the following. y=x3-3x+5 (a) Estimate the coordinates of the relative maxima, relative minima, or horizontal points of inflection by observing the graph. (If an answer does not exist, enter DNE.) relative maxima (X: Y) = ( ) relative minima (XI Y) = ( ) horizontal points of inflection (X, y) = ( ) (b) Use y' = f'(x) to find the critical values. (Enter your answers as a comma-separated list.) x: (c) Find the critical points. (Order your answers from smallest to largest X, then from smallest to largest y.) (x, y) = ( X (a) Estimate the coordinates of the relative maxima, relative minima, or horizontal points of inflection by observing the graph. (If an answer does relative maxima (x, y) = ( ) relative minima (x, y) = ( ) horizontal points of inflection (x, y) = ( ) (b) Use y' = f'(X) to find the critical values.
