<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:
