Remaining time Problem 2. (1 point) Let F(x) = f(t) dt, where f(t) is the graph in the figure. Find each of the following: A. F(2) = B. F (3) = C. The interval (with endpoints given to the nearest 0.25) where F is concave up: interval = 5 6 7 (Give your answer as an interval or a list of intervals, e.g., (-infinity,8] or (1,5),(7,10), or enter none for no intervals.) D. The value of x where F takes its maximum on the interval 0
