We have the following function: f (x) = x ^ 2 We have the following transformation: 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. Applying the transformation: y = (0.2x) ^ 2 The factor is: 1 / b = 1 / 0.2 = 5 Answer: b. expanded horizontally by a factor of 5
