Answer:
B) would be the most appropriate viewing window.
The graph of this function is shifted up 12 units from the parent graph; thus we need our y-value to go up past 10. This eliminates a and d.
The graph is also shifted to the right 5 units. This means we need to go past 5 on the x-axis to see the entire graph. This eliminates choice c, leaving us with b.
