How do you find the domain of the rational expression x over 3 ? (x)/(3)

Question

How do you find the domain of the rational expression x over 3 ?

`(x)/(3)`

Answer 1

We have to find the domain of the given rational expression
`(x)/(3)`

Since, Domain of a function is the set of values for which the function is real and defined.

Here, for any value of x the value of y will be always real and defined.

So, we can say that the domain of the rational expression
`(x)/(3)` is
`(-\infty ,\infty )` or we can say the domain of the rational expression is
`-\infty <x<\infty`
