Absolute/Global Extreme Values (a simple & generalized perspective)

3 fully solved Questions: a step-by-step approach to easily determine the critical points (if any) for a function along with the type (local/relative maximum or minimum values). Focus on Global (absolute) extreme values in a to-the-point, technique-oriented manner without getting lost in excess peculiarities or an abundance of rules! *** Foundation video: https://youtu.be/fjCWGpMgDgw *** Clarification: around time 8:14 to 9:15, I present two pictorial examples, absolute value of x and parabolic curve, within a defined domain. Note a local or relative minimum is present despite my saying that only absolute/global extrema are seen. In both graphic cases, the vertex serves as both absolute minimum and relative minimum extremes, as well if the domain is further restricted to area in region of vertex of each function graph. 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.
