Find the Domain 144y^2+9

Problem

144*y2+9

Solution

1. Identify the type of expression. The expression 144*y2+9 is a polynomial in terms of the variable y

2. Recall the definition of a domain for polynomials. Polynomials are defined for all real numbers because there are no denominators that could be zero and no square roots of negative numbers to consider.

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

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

Final Answer

Domain: *(−∞,∞)
