Answer:

Step-by-step explanation:
In general, 
Substitute x = 2, y = 15
(1)
<u />
Substitute x = 1, y = 5
(2) 
Divide equation (1) by equation (2)

3 = b
Now substitute b = 3 in equation (2) to find k
5 = k(3)

Since we know the values for k and b, we now have the exponential function that passes thru (1, 5) and (2, 15)

6.2*10^-5 is the notation
