Find the Domain y=-9

Problem

y=−9

Solution

1. Identify the type of function. The given equation y=−9 represents a constant function.

2. Analyze the input variable. In a function of the form ƒ(x)=c there are no restrictions on the input x (such as division by zero or square roots of negative numbers).

3. Determine the set of all possible x values. Since the function is defined for every real number x the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
