Front

What is a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is a nonlinear function?

Back

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

Front

What does it mean for a graph to pass the vertical line test?

Back

If a vertical line intersects the graph at more than one point, it is not a function.
