A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc. Polynomial functions are expressions that may contain variables of varying degrees, coefficients, positive exponents, and constants.


A polynomial function in standard form is:

[tex]f(x) = a_n x^n+ a_{n-1} x^{n-1}+ ... + a_2x^2+ a_1 x + a_0.[/tex]

This algebraic expression is called a polynomial   in variable x.

Here,

  1. [tex]a_n, a_{n-1}, \dots a_0[/tex] are real number constants
  2. [tex]a_n[/tex] can’t be equal to zero and is called the leading coefficient
  3. n is a non-negative integer
  4. Each exponent of variable in polynomial function should be a whole number

From the problem,

a) [tex]3x^2-5x^2+7[/tex]

b) [tex]x^2+4x-2[/tex]

e)  [tex]x[/tex]

g) [tex]\frac{x^2}{3} +x-5[/tex]

h) [tex]7[/tex]
All five expressions above are polynomial since all of the variables have positive integer exponents.

But expressions like;

c) [tex]2x^{-4}+x^3[/tex]

d) [tex]6x^{\frac{1}{3}}-x^2-1[/tex]

f) [tex]x^3+x^{\sqrt{2}}+1[/tex]
are not polynomials, we cannot consider negative integer exponents or fraction exponent or division here.

So, functions that are not polynomial are C, D, and F.
