Which of the following is a polynomial? (a)x2+x+3 (b)x+x+2 (c) x (d) 0​

Answer» ONG>Answer:

A cubic POLYNOMIAL is a polynomial of degree 3, or in simplier terms highest power of x is 3.

It is of the form f(x)=ax

3

+bx

2

+cx+d where a,b,c,d BELONGS to real numbers.

We can see that in option A, a=1,b=3,c=−4 and d=3.

Rest of the options B, C, D have the highest degree as 2.

Hence, they are quadratic polynomials.
