Extrema, Inflections & Concavities Problem

Pentic = 5th order (highest degree of polynomial). The purpose of the channel is to learn, familiarize, and review the necessary precalculus and trigonometry/geometry topics that form a basis for calculus (with a focus on functions). Calculus topics include limits, derivatives, integrals, formula derivations, derivations/proofs, area/volumes of curves and calculus applications. Utilize simple and easy techniques to get the material across to you. Disclaimer: I am not a professor by profession.
