1. Problem Description
The problem asks us to determine a series of transformations that map Figure M onto Figure N. The available transformations are reflection over the x-axis followed by a translation. We need to specify the direction and magnitude of the translation.
2. Solution Steps
First, reflect Figure M over the x-axis. If a point on Figure M is , the corresponding point on the reflected figure will be .
Next, we need to find the translation needed to map the reflected Figure M to Figure N. We can observe that Figure N is to the left of where Figure M would be after a reflection over the x-axis. Thus we will need to translate the reflected figure left. Let's pick a point on Figure M, such as which is a vertex. The reflected point will be or . A corresponding vertex on Figure N is .
Let's examine the top vertex of Figure M. This point appears to be approximately . After reflection over the x-axis it becomes . A corresponding point in Figure N is near . Thus, the coordinate must go from to , which is a shift of units to the left.
Let's verify this with the rightmost vertex of M, which is near after reflection over the x-axis. The corresponding vertex of N is approximately . The x coordinate shift is to the left. The y-coordinate shift from the reflected image of M after shifting down 4 is what maps figure M to figure N. Since the question only allows movement along the x-axis (right or left), we will reflect over the x axis and translate left 14 units.
3. Final Answer
A reflection over the x-axis followed by a translation left 14 unit(s).
