yes, g’(3)=1/9. or well atleast it should.

because dy/dx=1/(dx/dy). so if f(x) is equal to y, then f’(x) or y’ is equal to dy/dx. however the inverse of f(x) is basically with in terms of x instead of y. so the derivative of the inverse of f(x) is dx/dy.

based on the previous information.

9=1/(1/9) so the (1/9) part is basically dx/dy or the derivative of the inverse function.
