Looks fine to me


(so far; it does say determine its nature)

As steve says; I'd probably go with trying x = 1.5 and x = 0.5 rather than finding d2y/dx2.

You have not finished the question. It says 'determine the nature " this is the difficult part.

You could consider d^2y by dx^2, but this is fairly complicated. I think in this case I would consider the sign of dy/dx in the vicinity of (1, e)

ok thank you, I just wanted to know that it was correct so far, cheers
