Homework Help: Finding the limit of a function

  1. Nov 4, 2008 #1
    1. The problem statement, all variables and given/known data

    lim x-1/1-x
    x-->-infinity



    2. Relevant equations

    none really



    3. The attempt at a solution

    Other questions relating to this part of limits have us factor out the x from the function. So when I take the x out of the function I get 1/-1 with a final answer of -1.

    Is this correct?

    You don't "take x out of the function." You note that the constant 1 and -1 are not relevant when x is very large. The equation reduced to x/-x = -1. There's your limit.
