<h2>
Answer with explanation:</h2>
We know that when we are given a inverse function as: 
Then we find the function by the method:
Put 
Then we switch the places of x and y and solve for y.
1)

Hence, we find the function as follows:

Then we switch for x and y

Hence, inverse function is:

2)

Hence, we find the function as follows:

Then we switch for x and y


Hence, inverse function is:

3)

Hence, we find the function as follows:

Then we switch for x and y


Hence, inverse function is:

4)

Hence, we find the function as follows:

Then we switch for x and y

i.e.

Hence, inverse function is:
