Artillerymen on a hillside are trying to hit a target on a mountain on the other side of a river. The shells path is modeled by the equation y= -80x^2 + 120x + 610. The left side of the river is at y = 0 and the target is at y = -2. (x is in kilometers, y is in meters)
a. How high above the river will the shell be when it crosses: the right riverbank (x=2) and the left riverbank (x=0)
b. Approximately where will the shell be when y = 130
c. A reconnaissance plane is flying over the river at a height of 660 meters above the river. Is it in danger of being hit by the shells fired along the given path?
