Quadratics Review

A golfer hit a golf ball from a tee box that is 6 yards above the ground. The graph shows the height (in yards) of the golf ball above the ground as a quadratic function of x. Where x is the horizontal distance (in yards) of the golf ball from the tee box.

What is the domain of the function for this situation?

• x ≤ 4

• x ≥ −4

• y ≤ 4

• y ≥ −4
