Recall, if a function, f(x) is shifted d units to the right along the horizontal axis, the new function would be
f(x - d)
Thus, for the function y = f(x - 2), it means that there was a horizontal shift 2 units to the right. Thus, we have
The graph of y = f(x - 2) may be obtained by a horizontal shift of the graph of to the right a distance of 2 units
