y axis | the vertical axis on a coordinate grid. |

quadrants | the four parts to a coordinate grid |

origin | the point 0,0 on a coordinate grid |

relation | a set of ordered pairs |

function | a set of ordered pairs where the x's do not repeat |

domain | the x values to a set of ordered pairs |

x axis | the horizontal axis on a coordinate grid |

range | the y values to a set of ordered pairs |

discrete | individual points that would be connected when graphed because not all rational values define the domain |

continuous | an infinite number of points that are connected when graphed because all real values can be defined in the domain |

ordered pair | a point in the form of x,y or x,f(y) |

variable | a letter used to a quantity in algebra |

vertical line test | a method used to determine if a graph is a function |

correlation | the trend for a set of data. it can be positive, negative, constant or no correlation |

independent variable | the x value of the function. also called the domain |

dependent variable | the y value of the function. also called the range |

the symbol f,x | means y |

Evaluate | to solve |

commutative property | the order of the numbers change |

associative property | the groups change(parenthesis change) |

distributive property | the numbers in a sum or difference are both multiplied by the same value |
