What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

What is an input-output table?

Back

A table that shows how each input is paired with an output, used to determine if a relation is a function.

Front

What does it mean for a relation to be 'not a function'?

Back

It means that at least one input is associated with more than one output.

Front

How can you identify a function from a set of ordered pairs?

Back

Check if any input value is repeated with different output values; if so, it is not a function.

Front

What is a mapping diagram?

Back

A visual representation that shows how each input is paired with an output.

Front

What is the definition of a domain in a function?

Back

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

Front

What is the definition of a range in a function?

Back

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

Front

What is a linear function?

Back

A function that graphs to a straight line, typically in the form y = mx + b.

Front

What is a non-linear function?

Back

A function that does not graph to a straight line, such as quadratic or exponential functions.
