Consider the following function. x2 x² - 49 (a) Find the critical numbers of f. (Enter your answers as a comma-separated list.) x = (0,0) = (b) Find the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation. If an answer does not exist, enter DNE.) (-∞, -7) U(-7,0) (0,7) U (7,00) increasing decreasing X (c) Apply the First Derivative Test to identify the relative extremum. (If an answer does not exist, enter DNE.) relative maximum (x, y) = (DNE * ) relative minimum (x, y) = DNE )
