Question

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells xx shirts can be found using the function f(x)=7x-80. Find and interpret the given function values and determine an appropriate domain for the function.

Answer 1

see explanation. Hope this helped :)

Explanation:

The interpret of the given function values and determine an appropriate domain for the function should be explained below:

The following information should be considered:

f(−5)= −150, meaning if the company sells -5 shirts, they would make a profit of -150 dollars. This interpretation does NOT make sense in the context of the problem.

f(7)= −30, meaning if the company sells 77 shirts, they would make a profit of −30 dollars. This interpretation makes sense in the context of the problem.

f(10.5)= 5, meaning if the company sells 10.5 shirts, they would make a profit of 5 dollars. This interpretation does NOT make sense in the context of the problem.
