step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

so, it becomes,

hence, first option 'a'   is correct.
