Consider the following function. F(x) = JAX+ 1, x5 -1 1x 2 - 4, X>-1 (a) Find the critical numbers of f. (Enter your answers as a comma separated list.) X = (b) Find the open intervals on which the function is increasing or decreasing. Enter your susthe interval notation. If an answer does not exist, enter DNE.) increasing decreasing (c) Apply the First Derivative Test to identify the relative extremum, (If an answer does not exist. enter ONE. ] relative maximum (x, y) = relative minimum (x . V )
