Math Problem Statement
The table below gives selected values for a differentiable and increasing function f and its derivative. if g(x) = f^-1(x). what is the value of g'(2) =
x = 0, 1, 2
f(x) = 49, 2, -1
f'(x) = 0, -8, -80
Solution
To solve for where , we can use the inverse function derivative formula:
In this case, we need to find , which means we want the derivative of the inverse function at .
