Question

the height y,in feet,of a football x seconds after it is ththrown is modeled by the equation y=16x^2+24+1.what information does the zero of the equation 6=-16×^2+24x+1 represent?

Answer 1

They represent the two times the football is on the ground.

Answer 2

The zeros of the equation represent the two times (the equation of the model is quadratic) that the ball is on the ground, that is, the zeros are the values of x-variable (time, in seconds) for which y-variable (height, in feet) is equal to zero.
