What is a polynomial function?

A polynomial function in standard form must look like:
#f(x)=a_nx^n+a_(n-1)x^(n-1)+a_(n-2)x^(n-2)+...+a_2x^2+a_1x+a_0#
where
If you are not familiar with the notation,
Examples of polynomial functions in standard form:
#f(x)=-4x^5+7x^3-6x^2+4#
#g(x)=3x^4-4x^3+6x-9#
Examples of non polynomial functions:
#h(x)=4x^7-3x^5+sqrt(2x)-5#
#j(x)=-7x^3-2x^2+5/(x^3)#
#k(x)=4.5x^5-3x^2#
I'll leave it to you to figure out why they are non polynomial functions.
