The equation  has this graph: 



To shrink it horizontally by 1/3, we multiply the right side by the reciprocal of
1/3, which is 3.  So the equation is  which has this graph:



To translate it horizontally by 2 units left, we replace x in the right side by
(x+2).  So the equation is  which has this graph:
