Question

A polynomial of degree ________ is called a cubic polynomial.

• A. $0$
• B. $1$
• C. $2$
• D. $3$

Answer 1

Answer: (D)

$3$

The general form of cubic polynomial is $p\left(x\right)=a{x}^3+b{x}^2+cx+d$ where $x$ is a variable and $a,b,c,d$ are constants. The highest power of a cubic polynomial is $3.$

Hence, a polynomial of degree $3$ is called a cubic polynomial.
