Front

What is the definition of function?

Back

Every input has only ONE output.

Front

Is this table a function or not a function?

Back

Not a Function.

Front

Is this graph a function or not a function?

Back

Function.

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a relation in mathematics?

Back

A set of ordered pairs, where each pair consists of an input and an output.

Front

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

Back

Each output is paired with exactly one input; no two different inputs produce the same output.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for the function.
