Using limits, considering the end behavior of the function f(x), it is found that the correct statement is given as follows:
D. a is positive, and b is odd.
<h3>What is the end behavior of a function?</h3>It is given by it's limits as x goes to negative and positive infinity.
In this problem, we have that, considering the end behavior:
This will only be true if a is positive and b is odd, hence option D is correct.
