Homework Help: Calculus, Delta- Epsilon Proof Of Limits

  1. Feb 17, 2008 #1
    1. The problem statement, all variables and given/known data
    Is this the right direction to prove

    Given that , prove that . Using the delta epsilon definition to prove that means that, for any arbitrary small there exists a where as:

    If we choose any constant for (x) called C, as long as C does not equal zero, the equation follows:

    whenever , since f(x) as x goes to a is equal to L.

    Multiply the by the absolute vale of the constant C, , so you have

    Now the product of absolute values is equal to the absolute value of the products so,

    3. The attempt at a solution
