Question 1074629: Write an equation for the translation of y=5/x with an asymptote at x=-3 and y=-2.

Please help and show all work so I can try and understand how to do it.

You can put this solution on YOUR website!

Here's the graph of y%22%22=%22%225%2Fx.

 

It has asymptotes which are the x-axis (y=0) and the y-axis (x=0)
and we want to move the graph so that it has x=-3 and y=-2, which
are these green lines, as asympotes instead.

 

So as you see we want to shift the graph 3 units left and 2
units down.

So we replace x by (x+3) and add -2 to the right side:

 y%22%22=%22%225%2F%28x%2B3%29-2



So the new graph with equation y%22%22=%22%225%2F%28x%2B3%29-2 has the
green line as asymptotes.  The original graph is dotted in
light blue.

If you like you can combine the terms on the right side:

 y%22%22=%22%225%2F%28x%2B3%29-%282%28x%2B3%29%29%2F%28x%2B3%29

 y%22%22=%22%225%2F%28x%2B3%29-%282x%2B6%29%2F%28x%2B3%29

 y%22%22=%22%22%285-2x-6%29%2F%28x%2B3%29

 y%22%22=%22%22%28-2x-1%29%2F%28x%2B3%29

 y%22%22=%22%22%28-%282x%2B1%29%29%2F%28x%2B3%29

 y%22%22=%22%22-%282x%2B1%29%2F%28x%2B3%29

But that probably isn't necessary.
