where N is an odd number, the ends will act oppositely of each other
Ex. Graph:
where N is an even number, the ends will act the same as each other
Ex. Graph
The Second Factor in the finding the end behaviors is whether or not the leading coefficient is positive or if it is negative. this determines whether as X approaches infinty if Y will also approach infinty, or if it will approach negative infinty, and whether or not as -X approaches infinty if Y will do the same or approach positive infinty. This can be summed up graphically in the following way:
If leading coefficient of is negative and N is even
If the leading coefficient of is positive, and N is even
The same goes for odd functions, so if the leading coefficient of is negative and N is Odd
If the leading coefficient of is positive, and N is odd
