Answer:
Part 1) No
Part 2) Option 4. 
part 3) 
Step-by-step explanation:
Part 1) we have

Find the inverse of f(x) and then compare with g(x)
Let
y=f(x)

Exchange the variables x for y and y for x

Isolate the variable y


Let


therefore
the functions f(x) and g(x) are not inverses of each other
Part 2) we have

Let
y=f(x)

Exchange the variables x for y and y for x

Isolate the variable y


Let



Part 3) we know that
For
, 
so
For
, 
1 large drink cost $1.65
Work: 16.95 - 12.00 = 4.95 <- Cost of drinks
Then 4.95 divided by 3 = 1.65
So it is $1.65 per large drink.

Answer:
z = -16
Option c
Step-by-step explanation:
2= 10+z / -3
Multiply both sides by -3
2×-3 = 10 + z
-6 = 10 + z
Subtract 10 from both sides
-6 -10 = 10-10 + z
-16 = z
z = -16
Option c
