I need help on these 2 Calculus Questions:

WeBWorK 4 - Topics 8 - 9: Problem 5 (1 point) f(m) = m3 4.51:2 1296 + 3 3) Find f'(x). 1 ii! b) Identify the graph that displays f in blue and f' in red. c) Using the graphs of f and f', indicate where f is increasing and decreasing. Give your answer in the term of an OPEN interval. NOTE: When using inteNaI notation in WeBWorK, remember that: You use 'INF' for 00 and l-|NF' for 00. And use 'U' for the union symbol. Enter DNE if an answer does not exist. f is increasing on f is decreasing on i m I "i WeBWork 4 - Topics 8 - 9: Problem 6 (1 point) Suppose that on the interval I, f(a) is positive and concave up. Furthermore, assume that f"(x) exists and let g(x) = (f(x) )2. Use this information to answer the following questions. To answer the questions, choose your answers from the following list: CU (concave up), CD (concave down), f(x) , f'(x) , f"(x) , 0 , or 1 . a.) f"(a) > on I. b.) g"(x) = 2( A2 + Bf"(x)), where A = and B = c.) g"(a) > on I. d.) g(x) is on
