Question

Classify the following as a constant, linear quadratic and cubic polynomials:
$2-x^2+x^3$

Answer 1

We know that
(a) a polynomial in which exponent of the variable is zero is called a constant polynomial.
(b) a polynomial of degree $1$ is called a linear polynomial.
(c) A polynomial of degree $2$ is called a quadratic polynomial.
(d) A polynomial of degree $3$ is called a cubic polynomial.
Hence, given polynomial is a Cubic polynomial.
