Suppose that
f(x) = 3 x^5 - 5 x^4.

(A) Find all critical values off .
If there are no critical values, enter -1000.
If there are more than one, enter them separated by commas.

(B) Use interval notation to indicate where

** Note: ** When using interval notation in WeBWorK, you use
** I ** for ** -I ** for ** U ** for the union symbol. If there are no values that satisfy the
required condition, then enter "{}" without the quotation marks.
