NOTE: When using interval notation in WeBWork, remember that: You use 'INF' for ∞o and '-INF' for -0. And use 'U' for the union symbol. Enter DNE if an answer does not exist. f(x) X⁹ 9x a) Find the critical numbers of f. (1.-8)U(-1,8) (Separate multiple answers by commas.) b) Determine the intervals on which f is increasing and decreasing. f is increasing on: (-INF-1) U (1,INF) f is decreasing on: (-1,1) c) Use the First Derivative Test to determine whether each critical point is a relative maximum, minimum, or neither. Relative maxima occur at a (-1,8) (Separate multiple answers by commas.) Relative minima occur at x = (1,-8) (Separate multiple answers by commas.)
