Answer:
y = -4/36 * (x-6)^2 + 4
Step-by-step explanation:
The quadratic equation expressed in vertex from is
y = a(x-h)^2 + k
The vertex is
Vertex = (h,k) = (6,4)
This means
y = a(x-6)^2 + 4
To find a, we know that at 12 feet from the water jet, the height is equal to zero.
0 = a(12-6)^2 + 4
a = -4/36
Therefore, the equation is
y = -4/36 * (x-6)^2 + 4
Please see attached graph for reference.
