A golfer hits the golf ball. The quadratic function y = −16x^2 + 80x gives the time x seconds when the golf ball is at height 0 feet. How long does it take for the golf ball to return to the ground? HELP PLEASE!
1 answer:
You need to calculate the two zeros of the function. The first zero is the "start", the second zero is the "end" of the trajectory.

Answer:
first is 3.5, second is 1
Step-by-step explanation:

10.5/3 = x
3.5 = x
2(3.5) - 6
