Answer:
Step-by-step explanation:
On the blue curve, locate the point (0, 1). This same point on the red curve is located at (2, 3). Since the h value indicates side to side movement, AND the red graph has moved to the right, we subtract the x values, blue from red, because x values indicate side to side movement (while y values indicate up or down movement). 2 - 0 = 2, thus the red graph has moved 2 units, the last choice you're offered.
