need within 50 mins, dont need an explanation just the answer

Set f(x) = e3x' +8x You can retry this question below Question 1 Solve the equation f' (x) = 0. If there are Part 1 of 2 more than one solution, separate your answers with a comma. If there are no solutions, write DNE. Suppose f and f - are differentiable functions. Suppose f( - 8) = - 7 and f'( - 8) = 3. DNE Question 1 Part 2 of 3 Question 2 It can be shown that f is one-to-one on the ( f - 1 ) ' ( - 7 ) = entire real line. So, f has an inverse. Is f - differentiable Part 2 of 2 on the entire real line? f '(x) Question 2 Set h(x) = arctan ( 27 ) Yes No h' ( - 7 ) = Part 3 of 3 Approximate your answer up to two decimal places. Question 3 (f -1) ' (1) = Submit Question Hint: Compute f(0)
