Front

How can you determine if a graph represents a function?

Back

A graph is a function if each x value has exactly one y value.

Front

What is the definition of a linear function?

Back

A linear function is a function that graphs to a straight line.

Front

What is the definition of a nonlinear function?

Back

A nonlinear function is a function that does not graph to a straight line.

Front

What is the domain of a function?

Back

The domain is the set of all possible x values (inputs) for a function.

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs (x, y).

Front

What does it mean for a mapping to be a function?

Back

A mapping is a function if each input (x value) is associated with exactly one output (y value).

Front

What is the vertical line test?

Back

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