Chapter 2.6, Problem 14E
To determine

To determine the domain of a function.

Expert Solution

Answer to Problem 14E

The domain of the function k(x)=x+3x1 is {x|x3 and x1} .

Explanation of Solution

Given information:

The given function is k(x)=x+3x1

Calculation :

In the function k(x)=x+3x1 , we cannot take the square root of a negative number. So, x+30=x3 and a rational expression is not defined when the denominator is 0 so x1 .

Hence, the domain of the function k(x)=x+3x1 is {x|x3 and x1} .
