It is IMPOSSIBLE to do it without having the definition of the function f(x).


&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;- - - which is missed in your post. - - - 



Also, for what reason do you request f(6) twice ?


Is requesting one time not enough ?
