1. Consider the transformation that maps the graph of the function into the graph of the function
This transmormation has a rule:
(x,y)→(x+2,y)
that is translation 2 units to the right.
2. Consider the transformation that maps the graph of the function into the graph of the function
This transformation has a rule:
(x,y)→(x,y+3)
that is translation 3 units up.
Answer: correct choice is C.
Remember that to find the vertical asymptotes of rational functions, we just need to set the denominator equal to zero and solve for the variable, in this case 
, so lets do it:
As you can see, our rational functions has 2 vertical asymptotes:
and 
As you can see, our rational functions has 2 vertical asymptotes:
