comment Find the tangent at a homogenous point to a curve
You should write the definition of f as f[x_, y_, z_] := x^3 y + 7 x^3 z + 6 x^2 y^2 - x^2 y z + 8 x^2 z^2 + 10 x y^3 + 2 x y^2 z - x y z^2 + 2 x z^3 + 4 y^3 z - y^2 z^2 + 2 y z^3. The spaces between the variables are important; do not omit them.

Saving three characters when typing is always importatnt, right? Or at least an offering to the gods of tersity (sic), concisity (sic), and laconicity (sic) :-)

comment Graphics3D artifact in Mathematica 10.1 64bit Home Edition - Windows 7?
I'm voting to close this question as off-topic because the problem the user is experiencing can not be reproduced by others.

comment How to write an operator that acts on pure function (to give another pure function)
Why do you insist on pure functions? It seems to me that the operator you request should not have to distinquish between pure and ordinary functions.

It would be better if you would edit this question to state your problem in Mathematica code. The mixture of Mathematica notation and traditional form you have posted makes it harder, not easier, to understand what you are requesting.
