Consider the following function. f(x) = 4|x - 4| (a) Find the critical numbers of f. (Enter your answers as a comma-separated list.) (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.) (-∞0,4) [4,00) increasing decreasing (c) Apply the First Derivative Test to identify the relative extremum. (If an answer does not exist, enter DNE.) 4,4 relative maximum (x, y) = relative minimum (x, y) = DNE
