<em></em>
Step-by-step explanation:
First of all, let us have a look at the steps of finding inverse of a function.
1. Replace y with x and x with y.
2. Solve for y.
3. Replace y with
Given that:
Now, let us find inverse of each option one by one.
I. y = x, a(x) = x
Replacing y with and x with y:
x = y
x = =
Hence, I is true.
II.
Replacing y with and x with y:
=
Hence, II is true.
III.
Replacing y with and x with y:
Hence, III is not true.
IV.
Replacing y with and x with y:
Hence, IV is not true.
