From the question, we were told that if the parent function is y = 2^x. We are to determine which is the function of the graph.
The parent function is in this form:
y = ab^x
Where:
a = the y-intercept, when x = 0
In the graph, we can see that the y-intercept is at:
y = 1/2
y = 0.5
Therefore, y = 0.5(2)^x
So, the correct option i
