Find the Domain 1/(x+1)

Problem

1/(x+1)

Solution

1. Identify the restriction for a rational function, which is that the denominator cannot be equal to zero.

2. Set the denominator expression equal to zero to find the excluded value.

x+1=0

3. Solve for x by subtracting 1 from both sides of the equation.

x=−1

4. Determine the domain by excluding this value from the set of all real numbers.

Domain={x|x≠−1}

Final Answer

Domain of 1/(x+1)=(−∞,−1)∪(−1,∞)
