MAT 220 Quiz 3 NAME 20 Points 3. (6 points) If h(x) = x f(x), SHOW ALL WORK a) Find h'(x). 8(x) 1. (2 points each) Let p(x) = f(x)g(x) and q(x) =. Use the given figure to find the indicated derivatives if they exist. If the derivative does not exist, indicate DNE and state why. Be sure to illustrate the use of the appropriate rule of differentiation. b ) Find h' (-2), iff (-2) = 5 and f' (-2) = -3. Kubik 1 2 Consentation; Work presented is beat, labelled, well organized and uses correct mathematical setation 8(x) Soclation: Work presented is complete (all relevant work is shown) and correct natical techniques are used wins major errors (depends on quantity of crop)) - D or I pix wine minor errors (depends on quietity of emars) - ? or ) pix Correcters' Answer is correct Answer is stated in a sentence if an application problems.
