Question

kristoff rents a kiosk in the mall to open an umbrella stand. he pays $6 to the mall owner for each umbrella he sells. the amount kristoff pays is given by f(x)=6x, where x is the number of umbrellas sold. graph the function and give its domain and range.

Answer 1

The domain is {Whole numbers x ≥ 0} and the range is {Whole numbers y ≥ 0}

How to determine the domain and the range of the function

From the question, we have the following parameters that can be used in our computation:

f(x) = 6x

By definition:

• The domain is the x values
• The range is the x values

Since, the function is a linear relation and he cannot sell negative number of umbrellas

The domain is {Whole numbers x ≥ 0} and the range is {Whole numbers y ≥ 0}
