Problem

7/5+28/x

Solution

1. Identify the expression as a sum of a constant term and a rational term.

2. Determine the restriction for the rational term 28/x noting that the denominator of any fraction cannot be equal to zero.

3. Set the denominator equal to zero to find the excluded value: x=0

4. Conclude that the domain consists of all real numbers except for x=0

Final Answer

Domain: *{x|x∈ℝ,x≠0}
