SUMMARY
The discussion focuses on finding the equation of a tangent line to the function f(x) = x² - 4x + 1 that is perpendicular to the line represented by x + 2y = 10. The slope of the given line is -1/2, leading to a tangent slope of 2. By calculating the derivative, f'(x) = 2x - 4, the user determines the point where the slope equals 2 to find the tangent line's equation. The user successfully concludes their solution without needing further assistance.
