Expert Solution

Answer to Problem 11E

The domain of the function f(x)=x+1x is {x|x0 and x1} .

Explanation of Solution

Given information:

The given function is f(x)=x+1x

Calculation :

In the function f(x)=x+1x , we cannot take the square root of a negative number. So, we must have x0 and 1x0=x1 .

Hence, the domain of the function f(x)=x+1x is {x|x0 and x1} .
