To determine

To calculate: the domain of the expression 2xx+1 .

Expert Solution

Answer to Problem 12E

The domain of the given expression is x[0,){1} .

Explanation of Solution

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 2xx+1 ,

Recall that the denominator should not be equal to 0

Therefore

  x+10

  x1

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

Therefore

  2x0x0

so the values of

  x[0,)

Therefore the domain of the expression will be

  x[0,){1}
