Let f(x) = 10x + 5 X (a) Find the interval(s) where f(x) is increasing. (Enter your answer using interval notation.) (-00, - 12) U( 72:00) X (b) Find the interval(s) where f(x) is decreasing. (Enter your answer using interval notation.) 1 1 12' 12 X (c) Find the x-value(s) of all local maxima of f(x). (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) 1 X = 12 X (d) Find the x-value(s) of all local minima of f(x). (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) 1 X = 12 X
