Is the following function growth or decay?

problem:

$\displaystyle f(x) = (4)^-^x$

Answer:Growth because a>0 and b >1. Now the graph is actually decaying(or just falling down), this gives me the notion I'm wrong.

I concur. This is decay. The negative in the exponent reflects the graph about the y-axis changing it from growth to decay.
