Algebra 2 Polynomial Functions
Lecture Description
Firstly, polynomial is an expression in which the terms are monomials and there can’t be a variable in the denominator. If it were, the expression wouldn't be a polynomial. It’s important to know what the degree of a polynomial is, and what a leading coefficient is. A function with a polynomial on its right side is called a polynomial function. This function can be evaluated for both numerical values and algebraic expressions. And a zero on a polynomial function is a point at which the graph of a function intersects the x-axis. Also, you'll learn about the end behavior of the graph of the function and see how its degree affects the graph.

In example one when you re-wrote the polynomial you dropped on of the operational signs; you wrote -12x^4-11x^3-7x^23x+9 not -12x^4-11x^3-7x^2+3x+9. The way you wrote it, it seems that the "3x" is multiplying the "-7x^2".
