Rational function is an function that can be defined by a rational fraction.
A function is called the rational function if it is written in the following form,
[tex]f(x)=\dfrac{P(x)}{Q(x)}[/tex]
For the given problem the rational function can be model for the total average cost per page for the first year as,
[tex]f(x)=\dfrac{2x}{1000} +3500[/tex]
The money spend on the computer and the office furniture is $3500.
The estimate costs per page is $0.02.
To write down this function is rational function we have the knowledge of the rational function.
Rational function is an function that can be defined by a rational fraction.
A function is called the rational function if it is written in the following form,
[tex]f(x)=\dfrac{P(x)}{Q(x)}[/tex]
In the given problem the cost of furniture and computer is fixed amount which is $3500. But the cost of per page vary with the number of page is being typed. So here we write a function with one variable.
[tex]f(x)=0.002x+3500[/tex]
As to make it the rational form the value of 0.002 can be converted into the fraction. For this we need to divide the value by 1000. Thus new function will be,
[tex]f(x)=\dfrac{2x}{1000} +3500[/tex]
Hence, for the given problem the rational function can be model for the total average cost per page for the first year as,
[tex]f(x)=\dfrac{2x}{1000} +3500[/tex]
