if the question says plot xy against 1/x, then what do we plot at y and what at x axis?

plot the variable before against on y axis and plot the one after against on the x axis!

 

[Snowysangel]

When do we use double differentiation (d2y/dx2)...is it to find the turning point? I feel like I'm forgetting everything :/

xy at y and 1/x at x I think.

It is to find the nature of the turning point. Maximum or minimum.
