range | the y values to a set of ordered pairs |
discrete | individual points that would not be connected when graph because not all rational values define the domain |
continuous | an infinite number of points that would not be connected when graphed because all real values can be defined in the domain (hours worked and pay) |

variable | a letter used to represent 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 |
