Q#1

Use the graph of the function to answer each question. (221 s x 5 2n) f(x) = cot(x) (a) Find all x-intercepts of the graph of y = f(x). (Enter your answers as a commaseparated list. If an answer does not exist, enter DNE.) X= (b) Find all y-intercepts of the graph of y = f(x). (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) y= (c) Find the intervals on which the graph of y = f(x) is increasing and the intervals on which the graph of y = f(x) is decreasing. (Enter your answers using interval notation. If an answer does not exist, enter DNE.) decreasing (d) Find all relative extrema, if any, of the graph of y = f(x).
