What it says is: Determine the xcoordinates of the points of inflection for the graph of f(x). so I took the derivative of f(x)=9e and I got 0, how am I supposed to get a point of inflection from this?

Best ResponseYou've already chosen the best response.0wait, i forgot to say something, I know that the point of inflection is the derivative of the function twice, and that is what 9e is, I had already taken the derivative once. :)

Best ResponseYou've already chosen the best response.0For inflection points you want to see when the curvature changes. That means that the second derivative changes sign.

Best ResponseYou've already chosen the best response.0Yep, but there is no x to set equal to x, sooo what do I do?

Best ResponseYou've already chosen the best response.0And you got 9e when you took the derivative?

Best ResponseYou've already chosen the best response.0the i plugged in 1 for x for some odd, odd, odd reason.

Best ResponseYou've already chosen the best response.0If the derivative were 9e, then I should be able to integrate 9e and get back to the original function plus a constant. But the integral of 9e is 9ex
