I need help in solving the following questions. (mathematically)

FRQ #1: Let f be a function defined on the closed interval [-5,5] with f(1) =3 . The graph of f', the derivative of f, consist of two semi circles and two line segments, as show below. 2 (2, 2) -2 -1 0 3 4 5 (5, -1) -21 Graph of f' a. Find all values x at with f has a relative maximum. Justify. b. Find all values x at which the graph f has a point of inflection. Justify your answer. c. Find all intervals on which the graph of fis concave up and also has a positive slope. Justify. FRQ #2: Let f be a twice-differentiable function such that f(2) =5 and f(5) =2. Let g be the function given by g (x) = f(f(x)). a. Explain why there must be a value c for 2
