Composite function: Combination of 2 functions where the input of the second is the output of the first.
Composition Suppose two functions f and g, where the range of g is a subset of the domain of f. Then the composition of f of g is f[g(x)].
Factoring: The process to brake a polynomial down into the product of several factors.
Factors: All whole numbers that are multiplied together to yield another number.
Factored Form: Any polynomial that is written as the product of polynomials of lower degree that may be obtained from the original polynomial.
Function: A relation of the type that has exactly one value in the domain (independent variable) matching a value in the range (dependent variable).
Function notation: A function written with the symbol f(x) instead of y. It is read as f of x.
Identity function: A function for which the input is equal to the output. In other words a function where x-coordinate is equal to the y-coordinate for all the domain of the function.
Inverse functions: Two functions are inverses if and only if both of their compositions result in the identity function. f[g(x)]=x and g[f(x)]=x.
Relation A set of ordered pairs.
