Is the input x or y?

Understand the Problem

The question is asking for clarification on whether a certain input is labeled as 'x' or 'y'. This implies a search for a rule or context about how inputs are categorized or identified.

More Information

In functions, x is typically considered the input or independent variable, and y is the output or dependent variable, because the value of y depends on x.

Tips

A common mistake is to confuse which variable is independent and which one is dependent. Always remember that in the context of functions, the independent variable (x) is what you control, and the dependent variable (y) is what changes in response.
