The maximum value of the function over its entire domain. (See Global Maximum)

The minumum value of the function over its entire domain. (See Global Minimum)

  |  The distance that a number is from zero on the number line. This must always be either zero or positive.

The domain for this combination function is , where A is the domain of function f, and B is the domain of function g. Example if:  and , then 

The number which when added to any other number, results in the other number. Zero(0) is the Additive Identity. (See Identity Element) 

The number which when added to a certain number, results in the Identity Element for Addition. (0)

A function which can be built using any algebraic operations. Rational functions all qualify, and in addition any roots can be included in the numerator and/or denominator.

A linear boundary which a graph approaches, but never touches. In the function , both the x-axis and y-axis are asymptotes of the function.

Special parametric curves that are often used in manufacturing, and in describing the shape of characters sent to laser printers. Bezier curves "smoothly" connect a set of points.

An "If-Then" Statement that is true in both directions.  Sample conditional statement: pq. This be thought of as If p, then q AND If q then p. It is often presented as p "if and only if" q (sometimes shown as iff). The biconditional statement is only true when both p and q have the same truth values.
