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).

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.

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 $\displaystyle f(x) = x^2 + \sqrt{1 + 2x}$?
