Expert Solution

Answer to Problem 7E

The domain of the given expression is xR{4}

Where R is real number

Explanation of Solution

Given information:

The given expression is provided below

  2x+1x4

Formula used:

The denominator part of the expression does not be 0 .

Calculation:

Consider the expression as,

  2x+1x4

Recall that the denominator should not be equal to 0,

Therefore

  x40x4

So the domain part of the expression will not contain x=4 because if it contain then the given expression will does not exist.

The domain of the expression 2x+1x4 is

  R{4}

Where R belongs to real number
