Sharon owns a car lot in Virginia Beach. For every car that parks in her parking lot, she charges $5.00 per day. She uses this equation to determine her daily income: y = 5x, where x is the number of cars and y is the amount of money earned. What is true about this function?

Answer and Step-by-step explanation:

Given the function y = 5x where x is the total number of cars parked in her lot and y is the total money earned. Since x is the independent variable as the money earned, y, depends on the amount of cars parked, we can say that the domain (the actual values the independent variable can assume) of this function is:

x = {0, 1, 2, 3, . . .}

This is because x, the number of cars, can never be a negative number..

Also, the range, the set of all the values of the dependent variable y, is: {all the numbers divisible by 5, including 0}
