#### Solutions

Chapter 1.4, Problem 10E
To determine

## To calculate: the domain of the expression 1x−1 .

Expert Solution

The domain of the given expression is x(1,) .

### Explanation of Solution

Given information:

The given expression is provided below

1x1

Formula used:

The denominator part of the expression does not be 0

And the under root value should be greater than equal to 0 .

Calculation:

Consider the expression as 1x1 ,

Recall that the denominator should not be equal to 0

Therefore

x10

x1

Recall that the under root value is always greater than equal to 0

Therefore

x10x1

so the values of

x(1,)

Here, if x will contain 1 then the function will not exist.

Therefore the domain of the expression will be

x(1,)
