Find the Domain x^2=144

Problem

x2=144

Solution

1. Identify the type of expression provided. The expression x2=144 is a quadratic equation where x is the independent variable.

2. Determine the constraints on the variable x In a polynomial equation of the form ƒ(x)=c there are no square roots of negative numbers, no denominators that could be zero, and no logarithms.

3. Conclude the domain based on the properties of polynomials. Since x2 is defined for all real numbers, there are no restrictions on the values x can take.

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

Final Answer

Domain: *(−∞,∞)
