Use the data to determine which of the following functions relates X and Y
(plot the indicated variables and see which yields the most straight line):
Case | Function | Plot X Variable | Plot Y Variable |

1 | Y=AX+B | X | Y |

2 | Y=AX^{B} | Log(X) | Log(Y) |

3 | Y=AB^{X} | X | Log(Y) |

4 | X=AB^{Y} | Log(X) | Y |
