on the surface find a point on this plane where it is the closest to (0,0,0) i know we should find a function f(x,y) which is the distance between the point on the suface oand (0,0,0) how to find this f(x,y) ?

Minimise subject to Lagrange multiplier problem, now show us what you have done or explain where you are having difficulties. CB
