If (p(x)=0x^4+0x^2+9), what type of polynomial is it?

Answer and explanation

Correct answer: Constant polynomial

Terms with a zero coefficient contribute nothing to a polynomial and can be removed without changing its value. In the given expression, 0x^4 and 0x^2 are both zero terms. Thus p(x) = 0x^4 + 0x^2 + 9 simplifies to p(x) = 9. Since 9 is not zero and does not depend on x, it is a non-zero constant polynomial.

A constant polynomial has degree 0, but the question asks for its type. It is therefore a constant polynomial, so option C is correct. It is not the zero polynomial because its remaining value is 9, not 0. It is also neither linear nor quadratic, because no x or x^2 term with a non-zero coefficient remains after simplification.
