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