Which function below is shown on the graph?

For this case we observe the cut point with the y axis in:
 (0, 7)
 The function that complies with this is:
 y = 2 ^ (x + 2) +3
 We have then:
 y = 2 ^ (0 + 2) +3
 y = 2 ^ (2) +3
 y = 4 + 3
 y = 7
 
 The answer for this case is given by:
 y = 2 ^ (x + 2) +3
