Answer:
The domain is all real numbers.
The function is always decreasing
Step-by-step explanation:
Assuming the given function is

for

Then f(x) is an exponential decay function.
This means that, the domain will be all real numbers.
The range will be y<0
The y-intercept is (0,-1)
There is no x-intercept.
The graph is a decreasing function.
