A | B |

a set of ordered pairs | relation |

the first coordinate in the ordered pair | domain |

the set of second coordinates | range |

a relation that assigns exactly one value in the range to each value in the domain | function |

if any vertical line passes through more than one point of the graph, the relation is not a funcion | vertical line test |

an equation that describes a function | function rule |

when you use f(x) to indicate the outputs | function notation |

independent variable | the inputs (x) |

dependent variable | the outputs (y) |

direct variation | y=kx |

constant of variation | k |

directions: find the domain and range in the following set of data | list the numbers in order |

directions: determine whether each relation is a function | use a mapping diagram and see if any number repeats itself in the set of coordinates |

Evaluate f(n)=-3n-10 n=6 | fill in 6 for the n(s) in the equation and get the number |

mirror image | identity |

#'s on both sides of the equation not equal | no solution |

variable on one side/ # on other side is zero | solution |

a comparison of two numbers by division | ratio |
