Question

The domain of the rational function LaTeX: f\left(x\right)=\frac{9}{x-5}f ( x ) = 9 x − 5 is all real values of x such that LaTeX: x\\e

Answer 1

Step-by-step explanation:

In this exercise we have the following function:

`f(x)=(9)/(x-5)`

So the domain of this function is the set of all real numbers such that
`x=\\eq 5`

Why?

Remember that the domain of a function are those x-values for which the function is defined. In this case, for
`x=5` the function is undefined, therefore x can't be 5.
