The function f(t) = −5t 2 + 20t + 60 models the approximate height of an object
1 answer:
Plug in f(t) = 0. We do this because f(t) represents the height and a height of 0 means you're at the ground.
f(t) =-5t^2 + 20t + 60
0 = -5t^2 + 20t + 60
-5t^2 + 20t + 60 = 0
Now solve for t using the quadratic formula
