f and g are inverse functions. If 𝑓(1) = βˆ’2 and 𝑓′(1) = 4, find 𝑔′(βˆ’2).?

please explain how to solve this, I don't understand.Β

given a function which has an inverse so that ( x ,f ) isΒ  a point in graph of f then ( f , x) is a point on the graph of the inverse function x.......so f depends upon x while x depends upon f.....(df/dx)(dx/df) ≑ 1 ====> derivative of the inverse x(f) satisfies dx/df ≑ 1 / ( df/dx)....

g'(-2) = 1/f'(1) = 1/4
