Onto and One-To-One FunctionWhy is the following function (f(n) = n + 17), one-to-one, but not onto? The function should be able to take on values of (-inf,inf) in the codomain or range, correct? |

Re: Onto and One-To-One FunctionI don't know. What's the domain? You'll get different answers depending on whether it's N -> N or R -> R or something else. |

Re: Onto and One-To-One FunctionN -> N |

Re: Onto and One-To-One FunctionWhat value of n gives f(n) = 3? |

Re: Onto and One-To-One Functionfor the given fcn. (-14)... is that what you are asking? f(n) = n + 17; (-14) + 17 -> "3" |

Re: Onto and One-To-One FunctionBut -14 isn't in N. |
