The height in feet above the ground on an arrow after it is shot can be modeled by y = -16x^2 + 63x + 4. Can the arrow pass over a tree that is 68 ft tall? Explain the answer and give the height in feet the arrow can go.

The height in feet above the ground on an arrow after it is shot can be modeled by y = -16x^2 + 63x + 4.
Can the arrow pass over a tree that is 68 ft tall?
y = -16x^2 + 63x + 4
y = -(x - 4) (16 x + 1)
Explain the answer and give the height in feet the arrow can go.
