ANSWER
Translated 2 units in the negative y-direction that is, shifted 2 left.
Step-by-step explanation
Assuming we have g(x) = f(x) + c
if c > 0, it means the curve f(x) is translated c units in the positive y-direction
if c < 0, it means the curve f(x) is translated c units in the negative y-direction
But from the question, we are given:
g(x) = f(x) - 2
That is c = -2, therefore c < 0
This shows that f(x) translated 2 units in the negative y-direction.
Hence, the graph of f(x) translated to form the graph of g(x) by 2 units in the negative y-direction that is, shifted 2 left.
