Question 9, 4.3.9 HW So Part 1 of 2 Points: 0 of 1 Even though the limit can be found using the theorem, Limits of Rational Functions at Infinity and Horizontal Asymptotes of Rational Functions, use L'Hopital's rule to find the limit. lim X - 81 X-+3 X- 3 Apply L'Hopital's rule so that the lim x - 81 is not an indeterminate form of the type 0 / 0. X-+3 X-3 lim X - 81 lim X-+3. X- 3 x - 3Question 8, 4.2.35 HW Score: 0%, 0 of 19 points Part 1 of 3 O Points: 0 of 1 Find the intervals on which the graph of f is concave upward, the intervals on which the graph of f is concave downward, and the inflection points. f(x) = - x#+24x5-24x +19 For what interval(s) of x is the graph of f concave upward? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. (Type your answer in interval notation. Type an exact answer.
