Question

Which of the following expressions are polynomials and which are not (why?)
1/x^3 +x^2

Answer 1

Answer:

none shown

Step-by-step explanation:

1/x^3 = x^(-3) has a negative exponent. It does not match the requirement that exponents be a non-negative integer. Therefore, any expression containing 1/x^3 will not be a polynomial.
