Answer: 
Step-by-step explanation:
By definition the domain of an inverse function 
is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function 
, then to find the inverse function, follow these steps:
1. Make 
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with
. Then the inverse function is:
Answer:
true
Step-by-step explanation:
Answer:
1) x= 3/2= 1 1/2
2) x= 2/3
Step-by-step explanation:
1)How many times as heavy as Whiskers is Piglio?
a) Write a multiplication equation for the question.
2 2/3 kg * [x]= 4kg
b) Write a division equation for the question.
4/ 2 (2/3) = x
c) Is the answer greater than 1 or less than 1?
Ans) Greater than 1
d) Find the answer
4/ 8/3= x
x= 3/2= 1 1/2
Pigilo is 1 1/2 times as heavy as whiskers
2)How many times as heavy as Piglio is Whiskers?
a) Write a multiplication equation for the question.
4 kg * [x]= 2 2/3 kg
b) Write a division equation for the question.
2 (2/3)/4 = x
c) Is the answer greater than 1 or less than 1?
Ans) Less than 1
d) Find the answer
8/3/4= x
8/3 * 1/4= x
2/3= x
Whiskers is 2/3 times as heavy as Pigilo.
16. It's basically the problem you started with, but just reversed.
