John's monthly natural gas bill is based on his gas usage at a rate of $0.804 per hundred cubic feet of gas, and a facilities charge of $7.75.The function f(x) = 7.75 +0.804x, where x is the amount of gas consumed in hundreds of cubic feet, can be used to determine John'smonthly gas bill. What is an appropriate domain and range for this situation?

Respuesta :

As given by the question

There are given that function

[tex]f(x)=7.75+0.804x[/tex]

Now,

First find the domain of the given function.

Then,

The domain of the function, where the given function is defined.

So,

The domain is:

[tex](-\infty,\text{ }\infty)[/tex]

And,

The range of the function is defined for the set of values that correspond with the domain.

So,

The range of the given function is

[tex](-\infty,\text{ }\infty)[/tex]
