Curve Sketching Let f(x) = x . e* You may check your work on this problem using a graphing program. You must, however, show your work finding solutions by hand. a. Find any roots of f. b. Determine the end behavior (limits at +/- infinity) of f. c. Find any local maximums or minimums. d. Determine where f is increasing and decreasing. e. Determine where f is concave up and concave down. f. Sketch a graph of f
