calculus help with fundamental theorem

Please provide answers to questions 3, 4, and 5 only in the attached calculus homework sheet. The focus of these questions are on the fundamental theorem of Calculus, Part 1 and 2, differentiation and integration. I am in a time crunch so appreciate getting responses to these questions as soon as possible and before the end of the day, Tuesday, December 4th. The attached PNG file has the 3 questions that I am seeking an answer for, namely Question Number 3, 4, and 5. I also suggest that StudyPool removes the 100 character minimum if there is an attached document which clearly lists the questions, eliminating the need to write useless text like what I am writing here.
