Polynomial Functions Terms to Know
| Term | Definition |
|---|---|
| Leading Coefficient | The coefficient of the first term of a polynomial in standard form. |
| Constant or constant term | A term in a function or expression that does not contain a variable. |
| Factor | A number or expression that divides into a number or expression evenly (remainder of zero) |
| Standard Form of a Polynomial | When a polynomial is written so the terms are in order from greatest degree to least degree. |
| Perfect Square | A number whose positive square root is a whole number. |
| End Behavior | The trends in the y-values of a functions as the x-values approach positive and negative infinity. Where the graph is going up and down as the x-values go to positive and negative infinity. |
| Monomial | A number or product of numbers and variables with whole-number exponents. |
| Multiplicity | When a factor (x -r) appears more than once when a polynomial is factored it is said to have a multiplicity of the number of times it appears. |
| Polynomial | A monomial or the sum or difference of monomials. |
| Polynomial Function | A function made up of the sum or difference of monomials. |
| Synthetic Division | A shorter method of dividing a polynomial by a binomial (x - a) using only the coefficients of the polynomial. |
| Turning Point | A point on the graph that is a local maximum or minimum. It is where the graph will change directions (from increasing to decreasing or decreasing to increasing). |
| Discriminant | b^2 - 4ac |
