Answer:
It will be a horizontal shift of f, c units to the left.
Step-by-step explanation:
When we add a constant 'c' to an input of the function f(x), then there is a horizontal horizontal shift of f, c units to the left.
In other words,
Or
set x + c = 0
x = -c ( move left c units )
Therefore, it will be a horizontal shift of f, c units to the left.
