What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that result from using the function.

What defines a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, with a constant rate of change.

How can you determine if a relation is a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value). If any input has more than one output, it is not a function.

What does it mean for a function to be one-to-one?

Back

A function is one-to-one if each output (y-value) is paired with exactly one input (x-value), meaning no two different inputs produce the same output.
