Explanation:

To determine the correct definition of domain, we analyze each option:

• Option A: The domain of a function (or equation) is indeed the set of all valid input values (usually \( x \)-values) that can be used.
• Option B: An individual input value is not the domain; the domain is the set of all such values.
• Option C: Output values are the range, not the domain.

Answer:

A. Domain represents all of the input values that I can use in the equation.
