Critical Points and Relative Extrema Explained | Calculus I

For months, we practice how to compute derivatives. But eventually, the real power of calculus begins when we ask what derivatives tell us about a function. In this video, we’ll walk through: • What a critical number is • How to find critical points of a function • What relative maximums and minimums really mean • How critical numbers relate to relative extrema • Why the sign of the derivative matters Using a clear algebraic example and a visual look in Desmos, we’ll connect derivative calculations to function behavior — the point where calculus becomes more than just rules and procedures. If you’re in Calculus I and transitioning from computing derivatives to analyzing functions, this is a key conceptual step. Topics covered: Critical numbers First derivative test Relative extrema Increasing and decreasing intervals Connecting algebra to graph behavior If this helped clarify things, consider subscribing — more calculus content coming soon.
