The initial height is 20 feet above the ground.
The function to model the velocity is
Where <em>s</em> represents the distance in feet.
Mathematically, this function has all real numbers as a domain. However, that will no make sense for this situation, because it would use negative numbers for the distance <em>s</em> which does not make sense.
Therefore, the domain, in this case, would be all real numbers greater than or equal to zero, but less than or equal to 20.
<em>The reason for this domain is that the ball will go from 20 feet above the ground to zero feet on the ground.</em>

Using interval notation would be
Answer:
Step-by-step explanation:
We have to find the quotient of the following division, .
Now,
= {Since all the terms in the expression are in product form, so we can treat them separately}
{Since we know the property of exponent as }
=
= (Answer)
{Since we know, }
