We are asked to write an exponential function of the form
The function passes through the following two points
(3, 2) and (6, 16)
Let us substitute these two points into the above equation.
For point (3, 2):
For point (6, 16):
Equate the two equations to solve for b
So, the value of b is 2
Finally, the value of a is given by
So, the value of a is 1/4
Therefore, the exponential function is
