Suppose that
f(x)=x−3x^1/3
(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 INF for ∞∞, -INF for −∞−∞, 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 =
