Answer:
A. 3 units left
Step-by-step explanation:
If we have a function g(x) = f(x + c), we can say that the function g(x) is the function f(x) shifted by c units left.
So, if g(x) = f(x + 3) then the graph of g will be shifted 3 units left compared to the graph of f.
Therefore, the answer is 3 units left.
