Use transformations of the standard cubic function, f(x) = x³, to graph the function h(x) = (1/6)x³. Which of the following correctly describes the transformation of the function f(x) to the function h(x)?
A. f(x) is horizontally stretched by a factor of 6 to obtain h(x).
B. f(x) is vertically stretched by a factor of 6 to obtain h(x).
C. f(x) is horizontally compressed by a factor of 6 to obtain h(x).
D. f(x) is vertically compressed by a factor of 6 to obtain h(x).
