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

What is the domain of the function?

• D:{ x is greater than or equal to 3}

• D:{x is less than or equal to 3}

• D:{all real numbers}

• D:{ x is all real numbers between and including -1 and 5}
