Question

Quizplus · Accepted Answer

A polynomial function is a function that can be expressed as a sum of power functions in which the exponents are all non-negative integers. A rational function is a function that can be expressed as a ratio of two polynomial functions. The given function contains terms with both positive and negative exponents, indicating it is not a polynomial function. However, it can be expressed as a ratio of two polynomial functions, making it a rational function. Therefore, the correct choice is D. The degree of the function is not relevant in this case.
