First, we rewrite both functions correctly:
f (x) = 0.5 ^ x
g (x) = 0.25 ^ x
We observe that they are exponential functions, where, rewriting:
f (x) = (1/2) ^ x
g (x) = (1/4) ^ x
We observe that both graphs present an exponential decay where, f (x)> g(x), since, the rate of change of f (x) (1/2) is greater than the rate of change of g (x) ( 1/4).
Answer:
as -> infinity, f (x)> g (x) *
