SUMMARY
The discussion focuses on finding the equation of the tangent line to the inverse function of f(x) = x³ + 2x² - x + 1 at the point (3, 1). The Inverse Function Theorem is applied, yielding the derivative 1/(3x² + 4x). By substituting x = 3, the slope of the tangent line is determined to be 1/21. The final equation of the tangent line is expressed as y = (1/21)x + 6/7.
