Solution
Solution Steps
To determine the domain of the function \( g(x) = \frac{2}{x+1} \), we need to identify the values of \( x \) for which the function is defined. The function is undefined when the denominator is zero.
Solution Approach
Identify the values of \( x \) that make the denominator zero.
Exclude these values from the domain.
Step 1: Identify the Function
The function given is \( g(x) = \frac{2}{x+1} \).
Step 2: Determine Where the Function is Undefined
To find the domain, we need to determine where the function is undefined. The function is undefined when the denominator is equal to zero:
\[
x + 1 = 0
\]
Solving for \( x \) gives:
\[
x = -1
\]
Step 3: State the Domain
The domain of the function includes all real numbers except the value that makes the denominator zero. Therefore, the domain is:
\[
\text{Domain} = \mathbb{R} \setminus \{-1\}
\]
This can be expressed as:
\[
\text{Domain} = (-\infty, -1) \cup (-1, \infty)
\]
Final Answer
The domain of \( g(x) \) is \(\boxed{\text{All real numbers except } x = -1}\).
