Question:

The curve C with equation y = f(x) is shown in the diagram, where

The curve has a local minimum at A and a local maximum at B.

a. Show that the x-coordinates of A and B satisfy the equation tan 2x = −0.5 and hence find the coordinates of A and B.

b. Using your answer to part a, find the coordinates of the maximum and minimum turning points on the curve with equation y = 2 + 4f(x − 4).

c. Determine the range of values for which f(x) is concave.
