NOTE: When using interval notation in WeBWork, remember that: You use 'INF' for ∞ and '-INF' for -∞. And use 'U' for the union symbol. Enter DNE if an answer does not exist. a) Find the critical numbers of f. b) Determine the intervals on which f is increasing and decreasing. f is increasing on: f is decreasing on: f(x) = x² - 9x (Separate multiple answers by commas.) c) Use the First Derivative Test to determine whether each critical point is a relative maximum, minimum, or neither. Relative maxima occur at x = (Separate multiple answers by commas.) Relative minima occur at x = (Separate multiple answers by commas.)
