What it says is: Determine the x-coordinates 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?

wait, 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. :)
For inflection points you want to see when the curvature changes. That means that the second derivative changes sign.
Yep, but there is no x to set equal to x, sooo what do I do?
