Question 1192394
The height h (in feet) of a water balloon can be modeled by h(x) = -3x^2 + 24x + 11, where x is the horizontal distance (in feet) from the launch pad.
The launchpad is adjusted so that the water balloon lands exactly 9 feet away from the launchpad.
 Write a function that models the new path of the water balloon. 
:
We should be able to do this by changing the coefficient of x^2 of the given equation: 
x=9, y=0
a*(9^2) + 24(9) + 11 = 0
81a + 216 + 11 = 0
81a = -227
a = -227/81
a = -2.802
new equation
h(x) = -2.802x^2 + 24x + 11
