f and g are inverse functions. If π(1) = β2 and πβ²(1) = 4, find πβ²(β2).?
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) β‘ 1 ====> derivative of the inverse x(f) satisfies dx/df β‘ 1 / ( df/dx)....

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