Find the Domain y=2x-1

Problem

y=2*x−1

Solution

1. Identify the type of function. The given equation y=2*x−1 is a linear function, which is a specific type of polynomial function.

2. Analyze the expression for any restrictions. For a real-valued function, restrictions typically occur if there is a denominator (which cannot be zero) or an even-indexed root (where the radicand must be non-negative).

3. Determine the domain. Since there are no fractions, square roots, or logarithms in the expression 2*x−1 the variable x can take any real number value.

4. Express the domain in interval notation. The set of all real numbers is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
