a soccer ball is kicked from the ground. after travelling horizontal distance of 35m,it just pass over a 1.5m tall fence before hitting the ground 38m from where it was kicked. Determine the equationi of a quadratic function that can be used to model the parabolic path of the ball.

math 
Reiny,
since the xintercepts are 0 and 38
we can create the equation to be
height = a(x)(x38)
but when x = 35 , height = 1.5
1.5 = a(35)((3538)
1.5 = a(105)
a = 1.5/105 = 1/70
height(x) = (1/70)(x)(x  38)
convert to any suitable form that is needed.
