Answer:
Thus, the 2nd or lower graph represents the graph of
.
The correct graph is also attached below.
Step-by-step explanation:
Given the function

Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.
now substituting x = 0 in the function

Apply the rule: 

Thus, the y-intercept is (0, 1)
Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)
Thus, the 2nd or lower graph represents the graph of
.
The correct graph is also attached below.
