Question

A football player tosses the ball through the air to a teammate. Could the path of the ball be described by the equation y = 0.5x2 + 0.3x + 2?

Answer 1

Explanation:

No; the graph for the path of a ball must be a parabola that opens downward, so if the equation is in the form y = ax2 + bx + c, a must be negative.
