Draw a graphic of the function using the basic elementary functions.
For example.
Draw [tex]f(x)=\frac{1}{x-1}-1[/tex]. I know that I will first draw the function 1/x (basic function) then shift the graph of the function 1/x for 1 on right of the x-axis, so I got the graph of the function 1/(x-1). Then shift the whole function for 1 up of the y-axis and I got the graph of f(x).
How will I do the same with [tex]f(x)=\frac{1}{x^2-1}-1[/tex].
I tried first with 1/x2 then I realized that I can't shift it for 1 on the x-axis? What's the problem? How will I draw the graph?
Thanks in advance.
