Explanation:

Since we are looking for an exponential equation in the form y = a·b^x, where b is the base of the exponential function, we can use the two given points to set up a system of equations and solve for a and b.

Using the point (3, 2), we have:

2 = a·b^3

Using the point (6, 16), we have:

16 = a·b^6

Dividing the second equation by the first equation, we get:

16/2 = (a·b^6) / (a·b^3)

8 = b^3

Taking the cube root of both sides, we get:

b = 2

Substituting this value of b into either of the two equations, we can solve for a. Using the first equation, we have:

2 = a·2^3

2 = 8a

a = 1/4

Therefore, the exponential equation that passes through the points (3, 2) and (6, 16) and has an asymptote of y=0 is:

y = (1/4)·2^x

or

y = 0.25·2^x
