<h2>Answer:</h2>
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
<h2>Explanation:</h2>Here we have the function:
that models the profit in dollars, where x is the number of memberships sold. In order to get the zeros we'll use the quadratic formula:
So the zeros are:
The zeros occurs when , so we can conclude that at those points there is no any profit.
In conclusion:
<em>x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.</em>
