For this case we have the following function:
 y = ^ 3√x
 Applying the following transformation we have:
 Expansions and horizontal compressions
 The graph of y = f (bx):
 If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b.
 y = ^ 3√0.5x
 Answer:
 A.It is horizontally stretched by a factor of 1 / 0.5
