Answer

$f(x)=3(2)^x$

Explanation

To solve this, we re using the standard exponential equation: $f(x)=ab^x$

Also, remember that $f(x)=y$

We know that our exponential function goes through the points (1, 6) and (2, 12), so we are going to replace the points in our stander exponential equation and solve for $a$ and $b$ :

For (1, 6)

$x=1$ and $y/f(x)=6$ , so:

$f(x)=ab^x$

$6=ab^1$

$6=ab$

$a=(6)/(b)$ equation (1)

For (2, 12)

$x=2$ and $y/f(x)=12$ , so:

$f(x)=ab^x$

$12=ab^2$ equation (2)

Replace equation (1) in equation (2) and solve for b

$12=ab^2$

$12=((6)/(b)) b^2$

$12=6b$

$b=(12)/(6)$

$b=2$ equation (3)

Replace equation (3) in equation (1) to find a

$a=(6)/(b)$

$a=(6)/(2)$

$a=3$

Now we can complete our exponential function:

$f(x)=ab^x$

$f(x)=3(2)^x$

We can conclude that the exponential function that goes through the points (1, 6) and (2, 12) is $f(x)=3(2)^x$
