f(1) =
I+2
(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) :
-1000
(B) Use interval notation to indicate where f(x) is increasing.
Note: When using interval notation in WeBWork, you use I for oo, -I for -00, and U for the union symbol. If there are.no values that satisfy the required condition, then enter "()"
without the quotation marks.
Increasing:
(-1,-2)
(C) Use interval notation to indicate where f(1) is decreasing.
Decreasing:
{1}
(D) Find the r-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 z = -1000
(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 z = -1000
(F) Use interval notation to indicate where f(z) is concave up
