Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers @ for which f(x) is a real number. X 2 4 Graph of fAP CollegeBoard Test Booklet Unit 2 Progress Check: FRQ Part A Let f be the continuous function defined on [-1, 8] whose graph, consisting of two line segments, is shown above. Let g and h be the functions defined by g(x) = vx2 - x + 3 and h(x) = 5e* - 9sinc. (a) The function k is defined by k(x) = f(x)g(x). Find k'(0). Please respond on separate paper, following directions from your teacher. (b) The function m is defined by m(@) = . Find m'(5). Please respond on separate paper, following directions from your teacher. (c) Find the value of & for -1
