Answer:
Domain = [0, ∞).
Step-by-step explanation:
he profit, in dollars, when the company sells x shirts can be found using the function
For x=0,
It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.
For x=5,
It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.
For x=10,
It means, if company sells 10 shirts, then company makes profit of $40.
Domain is the set of input values.
We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.
Domain = [0, ∞).
Therefore, the domain for the function is [0, ∞).
