question 11 is the graph
(10 points) The graph of a function f(x) is shown below. Sketch the graph of the derivative function f'(x), stating clearly the interval of increase/ decrease, and critical points. Read question 11 and sketch the derivative f'(x) of the function f(x). If you can sketch f'(x), it is fantastic. If you find it hard, then please answer the following questions. a. Is f'(-2) negative or positive or zero? Estimate the value of f'(-2). b. Is...
