(a) On what intervals is f increasing? (Enter your answer using interval notation.)
b)On what intervals is f decreasing? (Enter your answer using interval notation.)
For a i have (2,4)
and for be I have (0,2)U(4,6) i just want to make sure its right

Best ResponseYou've already chosen the best response.0f will increase on intervals where the graph is positive and decrease where the graph is negative.

Best ResponseYou've already chosen the best response.0For example the graph is positive from 0 to 1, so f increases on the interval [0, 1).

Best ResponseYou've already chosen the best response.0At what values of x does f have a local maximum or minimum? (Enter your answers as a commaseparated list.) Im not really sure how to solve for this part

Best ResponseYou've already chosen the best response.0yes, although I think you should use brackets [] for the 0 and 6 because of the closed circles.

Best ResponseYou've already chosen the best response.0local maximums and minimums are where the derivative is 0, so pick out the xintercepts of your graph
