Find the Domain 2/x

Problem

2/x

Solution

1. Identify the type of function. The expression 2/x is a rational function.

2. Determine the restriction for the domain. In a rational function, the denominator cannot be equal to zero because division by zero is undefined.

3. Set the denominator equal to zero to find the excluded value.

x=0

4. State the domain as all real numbers except for the value that makes the denominator zero.

Final Answer

Domain: *{x|x∈ℝ,x≠0}
