Consider the following function. x² f(x) = x²-49 (a) Find the critical numbers of f. (Enter your answers as a comma-separated list.) (0,0) x X = (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 (7,0) increasing decreasing (c) Apply the First Derivative Test to identify the relative extremum. (If an answer does not exist, enter DNE.) relative maximum (x, y) = DNE x ) relative minimum (x, y) = DNE
