you could swap x and y, and solve for the y

Answer 5

if you f[ f^-1(x)] then you should get "x"

Answer 6

also just about thinking what an inverse actually means

Answer 7

you are undoing something, you are solving an equation backwards kinda

Answer 8

alright thank you

should be obvious that it cannot be c.
