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 numbers greater than or equal to 0 and less than or equal to 7.66.

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

A quadratic function is graphed on the grid.

Drag and drop the answer choice that best represents the domain ​and range.

Domain: ​ (a)  

Range: ​ (b)

A golfer hit the 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 horizntal distance in yards of the golf ball from the box tee.

What is the domain of the function for this situation? ​ (a)  

• all real numbers

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

Which of these best represents the domain of f?

• all real numbers
