Consider the following function.
f(x) =
{4 â x2, x ⤠0
â9x, x > 0
(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 answers using 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 DNE.)
relative maximum (x, y) =
relative minimum (x, y) =
