General Idea:
Say if f(x) is the parent function, then f(x-c) represents transformation described as horizontal translation or shift of f(x) by ' c ' units to the right.
Applying the concept:
Here we are given a function 
, after the transformation of horizontal shift of 4 units to the right, the function will be given as below:
