As we know,
h(x) = a+bx-16x^2
a+b-16 = 148
4a+2b-64 = 272
solve that and you end up with
h(x) = 4 + 160x - 16x^2

A ball is launched from a slingshot. Its height, h(x), can be represented by a quadratic function in terms of time, x, in seconds.
After 1 second, the ball is 148 feet in the air, after 2 seconds the ball is 272 feet in the air.
Find the height in feet of the ball after 6 seconds in the air?
