YEAR 9 MATHEMATICS 26/10/2020 PROBLEM SOLVING SKILLS. REAL LIFE APPLICATION OF QUADRATIC FUNCTIONS Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are all examples of situations that can be modeled by quadratic functions. In many of these situations you will want to know the highest or lowest point of the parabola, which is known as the vertex. QUESTIONS 1. A toy rocket is fired into the air from the top of a barn. Its height (h) above the ground in yards after t seconds is given by the function h(t) = -5t² + 10t + 20. 1. What was the maximum height of the rocket? 2. How long was the rocket in the air before hitting the ground? 3. At what time(s) will the rocket be at a height of 22 yd?
