Question

a ball is launched from a sling shot. its heigh, h(x), can be represented by a quadratic function in terms of time, x, in seconds
after 1 second, the ball is 91 feel in the air; after 2 seconds, it is 164 feet in the air. find the height, in feet, of the ball after 3 seconds

Answer 1

because it is rising a height of 73ft per sec so the answer is 237ft

Answer 2

gothic's answer is unfortunately incorrect as this is a quadratic function. he/she is assuming it to be linear.

Answer 3

I'm getting H(x)=-9x^2 + 100x is the quadratic equation that satisfies the conditions.

Therefore H(3) = 219
