A football is kicked into the air. The height of the football can be modeled by the equation

Question

h=-16x^2+16x h = − 16 x 2 + 16 x where h is the height reached by the ball after x seconds. Find the values of x when h = 0.

Answer 1

h= -16x^2 +16x= -16(x)(x-1)=0

set the factors =0 solve for x

h=0 when x= 0 or 1 second
