A ball is thrown into the air. Its height above the ground, h (measured in feet), at any given time after the ball is thrown, t (measured in seconds), can be modeled using the quadratic function h(t) = -16t2 + 16t + 32. From what height above the ground was the ball thrown?

First of all....

Multiply...
