Demostración usando Teorema de Rolle, y teorema de valor intermedio

▼ IMPORTANT ▼ In this video we will make a proof about functions, using theorems about continuity and differentiation (differential calculus) that consists in showing that a cubic function f (x) = x ^ 2 + 2x + k cuts the x axis exactly once, for any value of k. Explained step by step. #Calculation #Functions #Continuity #Derivatives ---------- ** IMPORTANT LINKS ** Derivatives Course:    • Curso Completo de Derivadas   Integral course:    • Curso Completo de Integrales - Cálculo Int...   Functions:    • Funciones   Special Videos:    • Members-only videos   Mathematics Review Course (Pre-University)    • Curso de Repaso de Matemáticas   ---------- ** SEE ALL MY COURSES HERE **    / arquimedes1075   ---------- ** BIBLIOGRAPHY ** Calculus of a variable, James Stewart Calculus, M.
