Find the Domain (9x-12)-(5x-7)

Problem

(9*x−12)−(5*x−7)

Solution

1. Identify the type of expression provided. The expression (9*x−12)−(5*x−7) is a polynomial of the first degree (a linear expression).

2. Analyze the expression for any restrictions. Polynomials do not contain any operations that restrict the input values, such as division by zero (fractions with variables in the denominator) or square roots of negative numbers.

3. Determine the set of all possible input values for x Since there are no restrictions, the variable x can be any real number.

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

Final Answer

Domain of *(9*x−12)−(5*x−7)=(−∞,∞)
