If g(x) = 3x-1/x-1 and h(x) = 2x-1/x-3 find (g•h)^-1 which mean inverse x​

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
