Suppose that
f(x) = 3x^5 - 5x^4.
(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 this problem, you use ∞ for infinity, -∞ for negative 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) Use interval notation to indicate where f(x) is decreasing.
Decreasing: ____________
(D) 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 = ___________
(E) 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 = ___________
(F) Use interval notation to indicate where f(x) is concave up.
Concave up: _________
(G) Use interval notation to indicate where f(x) is concave down.
Concave down: ____________
(H) Find all inflection points of f. If there are no inflection points, enter -1000. If there are more than one, enter them separated by commas.
Inflection point(s) at x = ______________
(I) Find all horizontal asymptotes of f. If there are no horizontal asymptotes, enter -1000. If there are more than one, enter them separated by commas.
Horizontal asymptote(s): y = ______________
(J) Find all vertical asymptotes of f. If there are no vertical asymptotes, enter -1000. If there are more than one, enter them separated by commas.
