    Unhappy I have no idea how to do this one

    Use the Definition to find an expression for the area under the graph of f as a limit. Do not evaluate the limit.f(x) = x2 +
    1 + 2x
    , 4x6

    lim n
    n
    i = 1

    Again, we cannot help you identify your error or your confusion if you do not show us what you have done (or at the VERY least thought about).

    lim n → ∞

    If you really want our help then learn to post using LaTeX.
    I personally have no interest in trying to guess at what a question really means.
    What you posted above is total gibberish.
    Please learn to use LaTeX.

    I agree with Plato. You need to find another way to write your post. Do you have access to a scanner? Then you could write out your problem and post it.

    For now, is f(x) = x^2 + \sqrt{1 + 2x}?
