Question

F^-1(y)

F(x)= x/6+ 3

Answer 1

Hint: I'd be a lot more willing to address this question if only you'd include the directions.

Answer 2

y=x/6+3
y-3=x/6
x=6y-18
so
F(x)-1=6x-18

Answer 3

Please, include verbal explanations of what you're doing. The original problem posted lacks directions and your "solution" lacks explanations (as well as a conclusion).

Answer 4

@youngstar10 understand?
