Answer:
Initial value = 4
Step-by-step explanation:
we need to find the initial value of the exponential function shown on the graph
Initial value of the graph is the point where the graph crosses y axis
that is the point where x=0
When x=0 the value of y = 4
So the initial value of exponential function is 4
The graph of the exponential function is decreasing its going down
So it is an exponential decay function
