f(x)={|x-4|} ,x not equal to 4}
          x-4                              at x=4
       {0       , x equal to 4}
we have to find the left hand limit and right hand limit...
understood  how to find the right hand and left hand limit...
but i cannot simply understand the meaning of this question.
1)why is that 0(zero) written ?? and what is the whole use of-
{0       , x equal to 4}  ??
2) why is it written x equal to and not equal to 4... though we have to do the sum taking x=4 only???
sir, i studied limits on my own and could even solve some of the examples of rd sharma..
i have not taken any tuition... and looking forward not to take any..
sir, please could you clarify these conceptual doubts of mine????
