So, uh, what's a polynomial?
So, uh, what's a polynomial?
A polynomial is the sum or difference of monomials.

oh, right, so what's a monomial?
A monomial is an expression of the form k · x^n where k is a real number (any number that isn't imaginary) and n is a whole number (whole numbers are positive)
I once overheard a very excited conversation at a coffee shop, and they were talking about the degree of a polynomial ... what's that?
That's pretty much what you need to know about polynomials. Now, let's talk about how to evaluate a polynomial at given x-values.

Let's do a couple more examples on the board.
Let's do a couple more examples on the board.
Note: these could be written as "when x = -3," or as "find f(-3)." These are the same thing.
