Two projectiles are shot into the air over a lake. The paths of the projectiles are given by

(a) y = -0.0013x2 + x + 10 and

(b)

where y is the height and x is the horizontal distance traveled (both in feet). Determine which projectile travels farther by substituting y = 0 in each equation and finding x?
