The equation for this graph

is:

$\displaystyle

\frac {4\mid x + 1\mid(x +3 )(x - 1)^2}{(x + 1)^4(x - 3)}

$

I am trying to get rid of the absolute value of (x+1) to form a rational function. But without the absolute value, the left third of the graph is flipped over the x-axis. Is there a way to make this same graph without the absolute value?
