Your post is written INCORRECTLY.


The question asks about    f(g^(-1)(4)),   but the function  f  is not defined in the post,

and even is not mentioned in the  "given"  part. 



Such inaccurate writing shows and proves that the composer  DOES  NOT  understand what he  (or she)  writes.



Very sad . . .
