I dont understand how to find the inverese of a one to one function.

Find the inverese of the one to one function.

9. f(x)=-4x+7

Is the inverese suppose to be

f^-1(x)=x-7/-4?

12. f(x)= square root of x-8

I dont understand how to find the inverese on this one.

16. f(x)= 4/(5x-1)

I dont understand how to find the inverese on this one.
