Answer 1

@Preetha @nincompoop

Answer 2

\[f*f^{-1}=1\]

Answer 3

multip-ly both side by f^{-1}

Answer 4

can u do it @em2000

Answer 5

i dont know how

Answer 6

\[f^{-1} *f(2)=f^{-1}(\pi+7)\]

Answer 7

\[f^{-1}*f=1\]

Answer 8

on left side we will left with only 2

Answer 9

so \[f^{-1} (\pi+7)=???\]

Answer 10

@em2000

Answer 11

10.14??

Answer 12

on left side f inverse and f will cancel each other so we left with 2 only
