function definition

Dear Mathml users,

function definition
Which definition is better and in what case
they are used ? Is there any guideline ?

function f(x)
case1
  <m:apply>
    <m:ci>f</m:ci>
    <m:ci>x</m:ci>
  </m:apply>
case2
  <m:apply>
    <m:ci type="function">f</m:ci>
    <m:ci>x</m:ci>
  </m:apply>
case3
  <m:apply>
    <m:csymbol>f</m:csymbol>
    <m:ci>x</m:ci>
  </m:apply>

Best regardes,

Oka
