A ball was projected into the air with an initial upward velocity of 72 feet per second. The quadratic function graphed below shows the height, h, of the ball t seconds after it was projected into the air. What is the domain of the function for this situation?

Answer :

Answer

0 ≤ t ≤ 4.5

Step-by-step explanation

The domain of a function is all possible values of the x-variable.

In this case, the x-variable represents time, t, in seconds.

From the graph, the values of t go from zero seconds (included) to 4.5 seconds (included). Therefore, the domain is:

[tex]0\leq t\operatorname{\leq}4.5[/tex]
