It is not a function of only x- variable.
f=x^2+9y+2z^4
   if we want to find differentiation of this function,we need partial differentiation w.r.t (x).
\partial f/\partial x= \partial (x^2)/\partial x + \partial (9y)/\partial x +\partial (2z^4)/\partial x= 2x+0+0
     Hence, Final answer will be 2x.
