Algebra 1 Practice: Quadratics

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?

•  $0\le x\le230$  

•  $6\le y\le36$  

•  $0\le y\le36$  

•  $6\le x\le230$
