Find the Domain 2x+5-x-3

Problem

2*x+5−x−3

Solution

1. Identify the type of expression provided. The expression 2*x+5−x−3 is a polynomial (specifically, a linear polynomial after simplification).

2. Determine if there are any restrictions on the variable x Restrictions typically occur with denominators (which cannot be zero), even roots (where the radicand must be non-negative), or logarithms (where the argument must be positive).

3. Observe that this expression contains no fractions, roots, or logarithms.

4. Conclude that the variable x can be any real number, as the operations of addition, subtraction, and multiplication are defined for all real numbers.

Final Answer

Domain: *(−∞,∞)
