If f(x) = 8x + 1 and g(x) = 8(x - 2) + 1, how does the graph of g compare to the graph of f?
OA. the graph of g is the graph of f shifted up 2 units
OB. the graph of g is the graph of f shifted left 2 units
OC. the graph of g is the graph of f shifted down 2 units
D. the graph of g is the graph of f shifted right 2 units
