order  
  In a counting problem the order in which events occurs is sometimes important.  For example, when an outcome ABC is considered to be different from BAC the different arrangements of A, B, and C are being counted as different results and the order of the events is important in determining the number of results.  (pp. 523, 530)  See “permutations.”
ordered pair   
  A pair of numbers written (x, y) used to represent the coordinates of a point in an xy-plane where x represents the horizontal distance from 0 and y is the vertical.   The input and output values of a function or relation can be represented as ordered pairs were x is the input, and y is the output.
ordered triple   
  Three real numbers written in order (x, y, z) represent a point in space or replacement values for a situation involving three variables.  See “3‑dimensional coordinate axes.”  (p. 312)
orientation   
  Used informally in this course to describe some graphs.  For example the direction a parabola opens might be referred to as its orientation.   When describing the graph of a polynomial function, a positive orientation would mean the graph eventually continues upward as the value of x increases, as in the example above right.  A negative orientation would mean it eventually heads downward as the value of x continues to increase, as in the example below right.  (pp. 175, 445)

outcome   
  Used to describe the result of an event in counting and probability problems.  For example, when rolling one six-sided die, the possible outcomes are the numbers 1, 2, 3, 4, 5, and 6.  (pp. 497, 502, 510)
output   
  Used to describe the result of applying a function or relationship rule to an input value.  When a function is represented by a function machine the output is the number that comes out of the machine.  For the function f(x) = x2 − 73  when the input is 10, the output is 27.   Function notation shows how the function operates on the input to produce the output: f(10) = 102 − 73 = 27.  (p. 6)
