Please provide answers for these questions. I am checking them against Symbolab and WolframAlpha's final answers to see which site simplifies them the best, so no need to break them down (just provide the letter answer).

Use product rule to find the derivative of at) = (:32 4:1: + 2)(2:1:3 2:2 + 4). Select one: " a. m) = 103:4 363:3 + 242:2 + 4.1: 16 " b. f'(:r) = 2:1?1 322:3 + 241172 + 42? - 15 " c. f'(:1:)= 12:51 322:3 + 242:2 + 42: 16 d. f'(:r) = (2:1: 4)(6$2 211:) Find the value of f'(1)for g) = 1'13 Select one: _. a. _1 " b. 3 _.c_ 0 "d. 1
