Find the Domain (1+a)^2

Problem

(1+a)2

Solution

1. Identify the type of function. The expression (1+a)2 is a polynomial function (specifically a quadratic) in terms of the variable a

2. Determine if there are any restrictions. Polynomials do not contain square roots of negative numbers, logarithms of non-positive numbers, or divisions by zero.

3. Conclude the domain. Since there are no values of a that make the expression undefined, the domain consists of all real numbers.

Final Answer

Domain:(−∞,∞)
