Formula and explanation

Given that the function y = f(x) is differentiable at the point x₀, the equation of the tangent line to the curve at the point (x₀, f(x₀)) is: y - f(x₀) = f'(x₀)(x - x₀) Applicable Condition: The function f(x) is differentiable at x₀. Brief Explanation: This is a direct application of the point - slope form of a line, where the slope is given by the derivative f'(x₀).
