Do not use technology. The graph of a continuous function f is shown. The three regions between the graph of f and the x-axis are marked A, B, and C, and have unsigned areas 6.5, 5, and 16.5, respectively. Let F(x) be an antiderivative of f that is differentiable on (0, 4) and with F(1) = 8. C A 3 (a) Find F(0) and F(4). F(0) = F(4) = (b) What is the minimum number of times F equals 4 on the interval [0, 4]? (c) Find all intervals where F is increasing. (Enter your answer using interval notation.) Justify your answer. O F is increasing where F(x) is concave upward. O F is increasing where f(x) > 0. O F is increasing where f(x) is increasing. O F is increasing where F(x) > 0. O F is increasing where f(x) is concave upward
