Question

what does y=f^-1(x) mean?

Answer 1

I think it means the inverse function. Does that make sense?

Answer 2

Is it y=f^(-1)x or y =f^(-1x)

Answer 3

so a reflection right?

Answer 4

nope its the inverse. Example y=2x the inverse would be y=1/2x

Answer 5

the -1 is outside the bracket and its an exponent

Answer 6

Inverse function notation looks like\[f ^{-1}(x)\]
