A bаsebаll is hit frоm а height оf 1 m. The height, h, оf the ball in metres after t seconds can be modelled by the relation h = –6t2 + 12t + 1. a) Use partial factoring to determine the maximum height reached by the ball. (4 marks) b) How long after the ball was hit, did it reach the maximum height? (1 mark)
