19. Use the graph below to answer the following questions. (4, 4) 10 6 12 -4- (-4, -4) (8, -4) (12, -4) Graph of f' The figure above shows the graph of f', the derivative of a differentiable function f on the interval [-4, 12]. It is given that f(1) = 7. a) What is the value of f"(2)? Show your work or explain why you cannot find this value. (2 points) you can't find this value because it's a corner with a sharp Corner b) For what value(s) of x does f have a maximum? Justify your answer. (2 points) at b because f is going tram's positive to negative on xaxis c) The function g is defined as g(x) = x f(x). Find the slope of the line normal to g(x) at x = 1.(4 points). 7 - 4
