Question 9
- If y = 2x2 – 5x + 3 is expressed in the form y = p(x + q)2 + r, where p, q and r are
constants, find (q + r). - Find the area enclosed by the curves y = x2 – 3x + 2 and y = – x2 + 3x + 2.
Observation
The Chief Examiner reported that candidates performed fairly well while attempting this
question. However, they did better in part (b) than in part (a).
