Consider the function ` f(x) = -5 (x - 3)^(2//3) `.
For this function there are two important open intervals:
` (-\infty, A) ` and ` (A,\infty) ` where
` A ` is a critical number.
Find ` A `
For each of the following intervals, tell whether ` f(x) ` is increasing or decreasing.
` (-\infty, A) `:
` (A,\infty) `:
