Answer:
270 Different Combo's
Step-by-step explanation:
They are inverses if f( (g(x)) = x
f((g(x)) = (1/2) (2x + 4) - 2 = x + 2 - 2 = x
so this proves that g(x) is the inverse of f(x)
the other inverse g((f(x)) should also be = x
The question can be solved as follows:

Hence the value of the given expression in scientific notation is expressed as:
A,C,B
A’s unit rate is 11.0667
C’s unit rate is 12.009
B’s unit rate is 12.5
