What does the graph of a cubic function look like?

Back

The graph of a cubic function can have one or two turning points and can extend to infinity in both directions. It typically has an S-shape.

Front

What is a turning point in the context of cubic functions?

Back

A turning point is a point on the graph where the function changes direction from increasing to decreasing or vice versa. Cubic functions can have up to two turning points.

How do you determine the turning points of a cubic function?

Front

What is the vertex of a cubic function?

Back

Cubic functions do not have a vertex like quadratic functions, but they have turning points where the direction of the graph changes.

Front

What is the difference between a cubic function and a quadratic function?

Back

A cubic function is of degree three and can have one or two turning points, while a quadratic function is of degree two and has one turning point (the vertex).
