We want to determine the domain of 
any function of the form
is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.
The domain of such functions is all real numbers.
That is for any x, the expression <span>3(2^-x) "makes sense".

Answer:
(a) and
Step-by-step explanation:
Required
Which of a to d has no solution
(a) and
We have:
Sole for m
Divide by 6
So, we have:
and
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
