Been doing these all day comfortably but like always he's threw a spanner in the works and complicated things... Got 10 of these very similar to do but if someone will point the way for the first one. I promise to do the other 9 myself...

Find the co-ordinates of the stationary points on the following curves. Determine whether each point is a local maximum or minimum point.

y = x^2 + (16/x)

All working shown please..
