f(x)=x^3 is the cubing function. Its graph begins (originates) in Q III, goes thru the origin (0,0), and continues to grow as it travels through Q I. Draw it.
The graph of f(x-4) has exactly the same shape. The only difference here is that the graph of f(x) = x^3 has been moved 4 units to the right, so that its horiz. intercept is (4,0).
