CRITICAL POINTS, LOCAL MAX MIN: Find a, b, c & d Using Points With Horizontal Tangent

Показать описание
In this video, I share with you steps for using derivatives concepts to find values of a, b, c and d such that graph of f(x) = 3x^4 + ax^3 + bx^2 + cx + d will have horizontal tangents at (-2, -73) and (0, -9). There is a third point that has a horizontal tangent. Find this point. For all three points, determine whether each corresponds to a local maximum, a local minimum or neither. @Math_Homework_Help #derivative #calculus #derivativeformulas #derivativesofthefunction #derivatives #polynomialfunctions #localmaximum #localminimum #algebra #algebraicequations #algebraicexpression #solvingequations #linearsystem #eliminationmethod #maths #mathematics #math #simplifyexpressions #linearsystems #slopeofaline #tangentline #function
