Find the Domain 19/x

Problem

19/x

Solution

1. Identify the type of function. The expression is a rational function, which is defined as the ratio of two polynomials.

2. Determine the restriction for the domain. For a rational expression to be defined, the denominator cannot be equal to zero.

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

x=0

4. State the domain. The domain consists of all real numbers except for the value that makes the denominator zero.

Final Answer

Domain: *{x|x∈ℝ,x≠0}
