Answer
3 is a constant polynomial.
Step by step explanation
Polynomials classified according to the number of terms.
i) Monomial - it will have only one term
ii) Binomial - it will have two terms.
iii) Trinomial - it will have three terms.
iv) constant Polynomial - it will have only a constant term.
If a polynomial containing one the constant term, then it is called constant polynomial.
Here 3 is a constant.
Therefore, 3 is called a "constant polynomial"
Answer: 3 is constant polynomial.
