A polynomial of degree ___ is called linear polynomial

A: 0

B: 2

C: 1

D: None of these




The general form of linear polynomial is P(x)=ax+b where x is a variable  and b is a  constant.

The first term of this polynomial has power 1 and therefore, the degree of the polynomial is 1.

A  polynomial of degree 1 is called linear polynomial.

Final answer:-

Hence,. The correct option is (C)i.e.1.
