The plane must be 3.38 miles away from the runway to begin the descent. The equation I used was "y = -0.1111111x + 0.3755682", 0.37~ being the height in feet (in miles) and -0.11~ being the descent. The x-intercept is located at 3.38.

Answer:
Step-by-step explanation:
To find the zeros, set y=-4(x - 3)2 + 8 = 0. Then -4(x - 3)^2 = -8, and:
4(x - 3)^2 = 8. Dividing both sides by 4 yields (x - 3)^2 = 2.
Taking the square root of both sides yields x - 3 = ±2, so that
x = 3 ±2, or x = 5 and x = 1. These are the zeros. The correct interpretatioon is A: where the daily profit is $0.
