    [SOLVED] limits and absolute value.

    Ive been stuck over this problem evaluating a limit with an absolute value. I checked online and found some very nice videos going over simple functions containing absolute values but the end all nicely without a 0 being in the denominator. Heres the problem:

    Find the limit, if it exists. (If it does not exist, enter NONE.)

    i figured it out, ill post the answer for reference.

    The limit doesn't exist, considering the limit of x--->-7 is different then x----> 7.
