Please answer the following in full:

1. The graph of the derivative of the function y = f (x) is shown below. 6- y 4- y = f'(x) 2- X -2- a) Determine the intervals when the derivative is i. Positive ii. Zero iii. negative5. The graph of the derivative of the function y = f (x) is shown below. y y = f(x) 4- 2- X 5 5 -2. a) Use the graph and the words negative, zero or positive to describe the values of the derivative and create a chart to show this for each interval or specific value of X. b) Analyse each interval or specific value of x to try to determine what the graph of y = f (x) looks like in that interval (or at the specific value of x) and then try to sketch a possible graph for y = f (x)
