Answer:
g(x) = x - 1
Explanation:
If a function is transformed by shifting k units to the left then the new function will be,
g(x) = f(x + k)
Therefore, from the question,
If a function 'f' is translated by 4 units to the left, image of the transformed function will be,
g(x) = f(x + 4)
g(x) = (x - 5) + 4
g(x) = x - 1
Therefore, g(x) = x - 1 will be the answer.
