This is a **rational** function

#### Explanation:

Having a polynomial in the numerator and the denominator (in such a way that they do not cancel out nicely) implies that you have a rational function.

You function has a polynomial of degree 2 in the numerator, and a polynomial of degree 3 in the denominator. These do not cancel out easily, and hence this implies that you have a rational function
