Question

1. in one sentence, explain why (b) is not a polynomial using a vocabulary word (denominator, exponent, variable, term, coefficient).

Explanation:

Assuming option (b) has a variable in its denominator, polynomials cannot have variables in denominators as this creates a negative exponent, which violates polynomial rules. Using the required vocabulary word "denominator", the core issue is the presence of a variable in the denominator.

Answer:

(b) is not a polynomial because it contains a variable in its denominator, and polynomials cannot have variables in denominators.
