Find the Domain y=x+7

Problem

y=x+7

Solution

1. Identify the type of function. The given equation y=x+7 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions. Polynomial functions do not have denominators containing variables (which could lead to division by zero) or even-indexed roots (which could lead to imaginary numbers).

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

Final Answer

Domain: *(−∞,∞)
