Lesson 's Glossary:
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.
