Answer 1

It's a complicated one, but what I did was try plugging in different values. Based on how it went from 3 to 18 to 108, it could be assumed it is being stretched by some factor. From x=0 to x=1, I figured it would be stretched by maybe a factor of 3, since anything to the 0 is 1.
Using the very basic general form of an exponential function:
\[\large y= n ^x \]
Assuming it is stretched by 3
\[\large y= 3(n)^x \]

Answer 2

I would say maybe
\[\large y= 3(6)^x \]

as if you plug in 0
\[\large y=3(6)^0 = 3\]
Plug in 1
\[\large y= 3(6)^1 = 18 \]
and plug in 2.. you could guess
