yes, when t = 0, h = -20+20 = 0
if you are graphing (t,h) yes
when t = 0, h = 0 (0,0)
h = 0 when t is 0 and 4 (0,0) and (4,0)
A football is kicked into the air. Its height in meters after t seconds is given by h=-5(t-2)^2+20
What was the height of the football when it was kicked?
Is it right the y intercept is 0,0 and x intercept is (0,0) and (4,0)?
