Key Attitudes
Math is about thinking creatively.
Key Ideas
The locations where the graph of a function crosses the x-axis can be used to find factors of the function.
A polynomial can have up to as many roots as its degree.
A polynomial function is smooth and has a domain of all real numbers.
The graphs of some polynomials functions do not have x-intercepts.
Key Skills
I can use a graphing calculator to locate x-intercepts of a polynomial.
I can use the x-intercepts to express a polynomial as the product of irreducible factors.
I can use long division to find factors of a polynomial.
