Question 969314
{{{f(x)=(somethingofx)/(someotherofx)}}}


Root at -1, hole or undefined for x at 1:

{{{f(x)=(stillmoreofx)((x-1)/((x-1))(x+1))}}}


Vertical Asymptote x=2.
{{{f(x)=(stillmoreofx)((x-1)/((x-1))(x+1)(x-2))}}}
Notice the degree of the denominator is three, and degree of numerator is one, maybe higher but less than three.  So far, the horizontal asymptote is 0; but you want it to be y=5.  
...  This is not yet finished, but maybe you see how to finish it.
