Final answer:
The end behavior of the rational function is that it approaches 0 as x approaches positive and negative infinity.
Step-by-step explanation:
The end behavior of a rational function is determined by the degrees of the numerator and denominator polynomials. In this case, the numerator polynomial has a degree of 2 (highest power of x is 2) and the denominator polynomial has a degree of 3 (highest power of x is 3).
Since the degree of the numerator is less than the degree of the denominator, the end behavior of the rational function is as follows:
As x approaches positive infinity, the function approaches 0.
As x approaches negative infinity, the function approaches 0 as well.
