Using a Derivative to find the equation of a tangent line.

Find the equation of the tangent line to the function y = x(x² - 3) where x = -2.

Steps:
① Find the derivative of the function.
② Use ① to find the slope at the point of interest.
③ Find the point at which the tangent touches the function.
→ Combine ② and ③ to find the line as y = mx + c
