Find the critical numbers of f (if any). Find the open intervals on which the function is increasing or decreasing and locate all relative extrema. Use a graphing utility to confirm your results. f(x) = x5 5 − lnx Critical numbers: (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) x = Increasing: (Select all that apply. ) none of these (0, 1) (1, ∞) (−∞, 0) (0, ∞) Decreasing: (Select all that apply. ) (−∞, 0) (0, 1) (0, ∞) (1, ∞) none of these Relative extrema: (If an answer does not exist, enter DNE. ) relative maximum (x, y) = ( ) relative minimum (x, y) = ( )
