Note: From the examples above we can make the following observations.

 

 

End Behaviours of Polynomial Functions:

 

By the term end behaviors, we mean we are investigating the behavior of the function (y) as x takes on

larger and larger positive or negative values (increases without bound or decreases without bound).
