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?

The graph of quadratic function f is shown on the grid.

Which of these best represents the domain of f?

• All real numbers

• All real numbers less than -3 or greater than 2
