Question
f(x) = 2xV4x² +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) =
%3D
(B) Use interval notation to indicate where f(x) is increasing.
Note: When using interval notation in WeBWorK, you use I for o, -I for –o, and U for the union symbol. If
there are no values that satisfy the required condition, then enter "{}" without the quotation marks.
