Which statement correctly describes the effect on the graph of f(x)= √(x + 1) + 2 when it is translated to f(x)= √(x + 1) − 3?
A. The graph is vertically compressed by a factor of 5.
Incorrect. The change is in k not a.
B. The graph is shifted down 5 units.
Correct!
C. The graph is shifted up 5 units.
Incorrect. Look at the k values again and think about where the graph starts to where it is shifted.
D. The graph is shifted 5 units to the left.
Incorrect. The change is in k not h.
