Answer:
The answer to your question is the last option g(x) = log (x - 4)
Explanation:
If we observe the graphs, g(x) was translated 4 units to the right then, we must look an equation with those characteristics.
g(x) = log(x) - 4 the graph is translated 4 units downwards
g(x) = log(x) + 4 the graph is translated 4 units upwards
g(x) = log(x + 4) the graph is translated 4 units to the left
g(x) = log(x - 4) the graph is translated 4 units to the right
