Find the Domain x^2+2x-3=0

Problem

x2+2*x−3=0

Solution

1. Identify the type of expression provided. The expression x2+2*x−3 is a polynomial.

2. Determine the domain of a polynomial function. Polynomials are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

3. State the domain in interval notation. Since the variable x can take any real value, the domain is all real numbers.

Final Answer

Domain:(−∞,∞)
