F(x)=4x3+8x.
(A) Find all critical values of f. If there are no critical values, enter -1000. If there are more than one, enter them separated by commas. Critical value(s) =
(B) Use interval notation to indicate where f(x) is increasing. Note: When using interval notation in WeBWorK, you use I for [infinity], -I for −[infinity], and U for the union symbol. If there are no values that satisfy the required condition, then enter "{}" without the quotation marks. Increasing:
(C) Find the x-coordinates of all local maxima of f. If there are no local maxima, enter -1000. If there are more than one, enter them separated by commas. Local maxima at x =
(D) Find the x-coordinates of all local minima of f. If there are no local minima, enter -1000. If there are more than one, enter them separated by commas. Local minima at x =
