Question

How to evaluate functions from a graph

**Problem Statement:**

Using the figure below, where \( f'(5) = 2.1 \), \( f'(10) = 3.0 \), \( f'(15) = 3.7 \), and \( f'(20) = 4.2 \), find \( \left( f^{-1} \right)'(20) \).

**Graph Description:**

The graph displayed is of the function \( f(x) \). The \( x \)-axis ranges from 0 to 25, and the \( y \)-axis ranges from 0 to 80. The graph is a curve that appears to be increasing, indicating that \( f(x) \) is a monotonically increasing function. The curve starts slightly above 20 on the \( y \)-axis when \( x = 0 \) and rises steeply, continuing past \( 60 \) on the \( y \)-axis as \( x \) approaches 20.

**Additional Information:**

- The derivative values at select points are provided:
  - \( f'(5) = 2.1 \)
  - \( f'(10) = 3.0 \)
  - \( f'(15) = 3.7 \)
  - \( f'(20) = 4.2 \)

**Task:**

Enter the exact answer.
