Find the Domain a^2+7a+10

Problem

a2+7*a+10

Solution

1. Identify the type of expression provided. The expression a2+7*a+10 is a polynomial.

2. Recall the definition of the domain for a polynomial function. A polynomial is defined for all real numbers because there are no denominators that could be zero and no square roots of negative numbers.

3. Determine the set of all possible input values for the variable a Since there are no restrictions, the domain is all real numbers.

4. Express the domain in interval notation or as a set. In interval notation, this is written as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
