Find the Domain y=x+30

Problem

y=x+30

Solution

1. Identify the type of function. The given equation y=x+30 is a linear function, which is a specific type of polynomial function.

2. Determine if there are any restrictions. For a function to have a restricted domain, there must be operations that are undefined for certain real numbers, such as division by zero or taking the square root of a negative number.

3. Analyze the expression x+30 Since addition is defined for all real numbers and there are no denominators or radicals involving the variable x there are no restrictions on the input.

4. State the domain. The domain of any polynomial function is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
