Application of derivatives

Suppose that
60 - 6
f(2)=
I +3
(A) Find all critical values of f. If there are no critical values, enter None. If there are more than one, enter them separated by commas.
Critical value(s) = none
(B) Use interval notation to indicate where f(2) is increasing. If it is increasing on more than one interval, enter the union of all intervals where
f(x) is increasing
Increasing: (-00,-3) (-3,00)
(C) Use interval notation to indicate where f(2) is decreasing. If it is decreasing on more than one interval, enter the union of all intervals where
f(x) is decreasing
Decreasing:
(D) Find the e-coordinates of all local maxima of f. If there are no local maxima, enter None. If there are more than one, enter them separated
by commas.
Local maxima at x =
(E) Find the c-coordinates of all local minima of f. If there are no local minima, enter None. If there are more than one, enter them separated by
commas.
Local minima at x =
(F) Use interval notation to indicate where f(2) is concave up.
