Polynomial is an expression that has more than two terms.

Examples:
   2x + x² - 4
   8xy + 3x³ - 9
   15a - 30b - ab
   a² + b + c³
   ab - bc + cd - de³

Polynomial can only be one term.  f(x) = 4x is a polynomial function.  F(x) = 7, 7 is a constant polynomial.  
f(x) = 7; where 7 is a constant polynomial.
Okay, ma'am. Thanks for the correction :) I appreciate it.
Because I know you are intelligent:-) Your examples are all correct :-) I am only adding some information :-) Keep posting answers :-)  
Thanks, ma'am. :D
