Answer:
Option D is correct
The exponential function is: ![f(x)= 4(3)^x](https://tex.z-dn.net/?f=f%28x%29%3D%204%283%29%5Ex)
Explanation:
An exponential function is in the general form is:
. ......[1]
Given the points (1,12) and (2, 36).
For the point (1,12),
Plug in x = 1 and y =12 in [1]; we get
or
12 =ab ......[2]
Now, for the point (2, 36);
Plug in x= 2 and y =36 in [1];
......[3]
Divide equation [3] by equation [2], we have
![\frac{36}{12}= \frac{ab^2}{ab}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B12%7D%3D%20%5Cfrac%7Bab%5E2%7D%7Bab%7D)
Simplify:
![3= b](https://tex.z-dn.net/?f=3%3D%20b)
Substitute the value of b in equation [2], to solve for a;
![12 =a\cdot 3](https://tex.z-dn.net/?f=12%20%3Da%5Ccdot%203)
Divide both side by 3 we get;
![\frac{12}{3}= \frac{3a}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B3%7D%3D%20%5Cfrac%7B3a%7D%7B3%7D)
simplify:
Then, put these a and b values in [1]; we get
The exponential function as: ![f(x)= 4(3)^x](https://tex.z-dn.net/?f=f%28x%29%3D%204%283%29%5Ex)
