Fundamentals of Mathematics

This same method can be applied to any equation; you just have to know the generalized shape. For instance,

• quadratic equations (the largest term is to the second power) forms a "U" like shape • cubic equations (the largest term is to the third power) creates a sideways "S" like shape • quartic equations (the largest term is to the fourth power) forms a "W" like shape

Cubic ( 3 )

Quartic ( 4 )

You can use the table method to graph any equation.
