Find an equation for each graph below. State the parent graph and describe the transformation.

1. 

   Hint (a):

   What is the parent graph?

   Hint (a):

   Rewrite the parent graph reflecting the horizontal shift.

   Hint (a):

   Rewrite the parent graph again to reflect the vertical shift.

   Answer (a):

   $y= \frac{1}{x}$

   Answer (a):

   $y = \frac{1}{x+2}$

   Answer (a):

   $y=\frac{1}{\textit{x} + 2} - 3$
