Answer:
C and E
Step-by-step explanation:
A polynomial is a function where the only operation is an exponent on the variable. It can have just one term or many terms. For example, x^2 is a polynomial but x^2 / x+3 is not since it also contains division. This is a rational. Using this definition then only C and E are polynomials.
Choice A has a rational term. This is not polynomial.
Choice B has an exponent of -2 which is actually division. This is rational and not polynomial.
Choice D has a radical term with the variable. This is not polynomial.
