Answer:
Horizontal translation in the
direction.
Step-by-step explanation:
A function of the form
experiments an horizontal translation when the following substitution is applied:
, where 
If
, the function is translated in the
direction, whereas
is the case for the function being translated in the
direction.
The effect on the graph can be defined by a composition between two function:
, 

The resulting expression represents a horizontal translation in the
direction.
Finally, we plot
(red) and
(blue) by a graphing tool and proved the certainty of this theory.
