Question 1163017
<br>
The format of the function as you show it is highly unusual; and I suspect it is not what you intended.  There should probably be some parentheses somewhere....<br>
Here is the function as you show it:<br>
{{{f(x)= 1/1-2/1+1/1-x}}}<br>
That simplifies to {{{f(x) = -x}}}<br>
That is not a very interesting function.<br>
I doubt that is what you meant....<br>
Re-post your question so we know what the question really is.<br>
