You can put this solution on YOUR website!
y=-2(4)^x
-----
What is the minimum value 4^x can have?
Answer: It can never be negative or zero,
but it can get closer and closer to zero
from the positive side as x gets closer
and closer to -infinity.

So, you multiply by -2; you will get negative
numbers that get closer and closer to zero from
the negative side.
---
So what is the horizontal asymptote?
It would have to be y = zero
