Problema Solution

A vacation home in Orlando, Florida, rents daily for $105 per day. The equation y = 105x gives the cost of renting the home for x days. What is the domain of this equation in real life terms?

The domain of a function is the set of all possible input values (in our case the "x" variable), which produce a valid output from a particular function (in our case y).

The domain of y = 105x is all real numbers.

In real life terms the number of days x can not be negative thus in real life terms the domain of x is all positive integer numbers.
