\"\"

\

The functions are \"\" and \"\".

\

Two functions \"\" and \"\" are inverse functions if and only if both of their

\

composite functions are the identity function.

\

Find the composite functions of \"\" and \"\".

\

Find \"\".

\

\"\"          (Rewrite the function)

\

\"\"             (Substitute \"\")

\

\"\"             (Substitute \"\")

\

\"\"                                      (Simplify)

\

\"\".

\

\"\"

\

Find \"\".

\

\"\"         (Rewrite the function)

\

\"\"            (Substitute \"\")

\

\"\"            (Substitute \"\")

\

\"\"                                      (Simplify)

\

\"\".

\

since \"\".

\

Therefore ,the functions are inverses.

\

\"\"

\

Yes, the functions are inverses.
