I believe that I have found the gradient. apart from that I am lost
Please quote me so I know you have replied
Correct, you've found f'(x), a function to find the gradient at a given point x.
The question talks about a point A, gives you some information about it and asks you to find something about it. How can you do those things? The function you've found plays a part and I think you will know how to use it when you need it. Becauae you've differentiated f (x) for some reason which is right, which leads me to suspect that you know you need to use it for something.

I only integrated because that was the topic in which the question was in. I really am lost xD.
I think it may be right. I'm just so lost and don't know what to do
Okay, let's assume it's right. The question asks you to find the normal to the curve at A.. you've found the point A. How do you find the equation of the normal to the curve at that point?
If it helps, past this point (given your previous working) it is no longer C3 knowledge but something you have covered in AS Maths.
