List all crtical points of f(r) Note: If there is more than one answer, witle them separated by commas (eg. 1, 2) If there are no critical points, enter none Now you want to fed any points z where f'(z) is not contnuous or not defined at at List such z values here Note: If there is more than one answer, wite them separated by commas (e g. 1,2), lthere are no such points, enter none (a) What are the open intervals on which f is increasing? f is increasing on the folowing intervals Note: Your answer should be a single interval, such as (0,1) or two or more intervals separated by "U for the union of two intervals, such as intinity, 2) U (3, 4) If there are no intervals on which f is decreasing, enter "none" (b) What are the open itervals on which f is decreasing? f is decreasing on the tollowing intervals Note: Your answer should be a single interval, such as (01), or two or more intervals separated by "U" for the union of two intervals, such as (infinity, 2)U (3, 4) If there are no intervals on which y decreasing ener-none" (c) Find the z values of all relative maxima of f Relative mas ma f occur at Note: If there are no relative maxima enter none Iif there is mone than one, enter the r-values as a comma separated Ist e g 1,2 id) Find the r values of all relative minima of f Relative minima of f occur at r Note: If there are no relative minima, enter "one i there is more tan one, ender the z-values as a comma separated steg 1,2 O B
