Final answer:
The cost of x months of basic cable can be calculated using the function f(x) = 80x.
Step-by-step explanation:
The subject of the question is Mathematics. The question asks about a cable company that charges $80 per month for a basic cable package, and it provides a function f(x) = 80x to represent the cost x for a month of basic cable.
To find the cost of x months of basic cable, you can substitute the value of x into the function f(x) = 80x. For example, if you want to find the cost of 5 months of basic cable, you can substitute x = 5 into the function and calculate f(5) = 80(5) = $400.
Therefore, the function f(x) = 80x represents the cost x for a month of basic cable.
