The curve C has equation y = (2x + 1)e^(-2x). (b) Hence find the exact coordinates of the stationary point of C.
- (b)Hence find the exact coordinates of the stationary point of C.[3]
Mark scheme
Marking points from the official mark scheme. The mark or mark type is shown in brackets.
- M1 for setting dy/dx = 0 and attempting to solve for x.
- A1 for x = 0 (seen or implied).
- A1 for y = 1, giving the coordinates as (0, 1).
