Answer:
the graph of g(x) is a horizontal transformation of f(x) 1 units to the left.
Explanation:
Given the parent function:

Rule of Horizontal transformation:
If y =f(x) , then y= f(x+k) gives a function that is translated k units towards the left side.
then;
By definition of horizontal translation:

Therefore, the graph of g(x) is a horizontal transformation of f(x) 1 units to the left.
