@xoya: what are the options 1 3 4 10 ?

anonymous · Answer

@sam801 the options are 1, 3, 4, and 10!

anonymous · Answer

the question is not clear for me, if it is like solve f - 1*x when x = 4
then it will be  f(4) - 1*4 
                       2*4 + 2 -4 
                       8+2-4
             which is equal to 6 but there is no option 6
