2 4 6 8 10 12 14 16. This is more likely an odd function but we will verify. In contrast to example 3 where the function has even powers this one has odd powers which are 7 5 3 and 1.

In contrast to example 3 where the function has even powers this one has odd powers which are 7 5 3 and 1. A function is even if the graph of the function is symmetrical about the y-axis or a function is eve. If the value of f x is the same as the value of f x for every value of x the function is even.

So the sign is inverted from one side of the x-axis to the other side. This is more likely an odd function but we will verify. Some of the odd numbers are.
