So I worked through the whole question here just to help myself and Ive included both parts in my attachments just in case. Part I surprised me slightly as I didn’t see the second derivative being a constant y value, but I suppose it makes things easier. I haven’t drawn a graph as it might end up quite convoluted but if this helps you, have a go yourself and I’d be happy to offer any improvements or corrections. I think the photos are pretty self-explanatory here but if you want me to explain a certain part just ask!
Hey dude, really sorry about this. Have been very overcome with work recently, but here’s a reuploaded photo of the completion to this problem.
My mistake, I meant to say part ii surprised me - my editor is bugging out a bit.
