TEKS A.6A: Quadratic Domain and Range

A ball is placed in a machine that throws the ball up in the air. The table represents some points on the graph of a function that models the ball's distance from the ground with respect to the time since the ball has been thrown.

What is the range for this situation?

• All real numbers less than or equal to 7.66

• All real numbers less than or equal to 1.25

• All real number greater than or equal to 0 and less than or equal to 7.66

• All real number greater than or equal to 0 and less than or equal to 1.25

A quadratic function is graphed on the grid.

Which answer choice best represents the domain and range of the function?

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, the horizontal distance in yards of the golf ball from the tee box.

What is the domain of the function for this situation?
