Use the domain, x-intercepts, y-intercepts, asymptotes, and +/- intervals to graph 

 

A +/- interval table can be created using the x-intercepts and the vertical asymptotes

Rearrange so that one side is equal to zero

 

Combine the expressions using the LCD

 

 

Create a +/- interval table using the zeroes of both the numerator and the denominator

 

When multiplying or dividing by a negative, reverse the inequality sign
