    How Do You Solve for Constants in a Cubic Function with Horizontal Tangents?

    If I am asked to find the constants a, b, c, d such that the graph of f(x)= ax^3 + bx^2 + cx+ d has horizontal tangent lines at the points (-2, 1) and (0, -3). I am not sure what to go about doing it...is that asking me to find what? (I don't know what do the constant stand for? in form of...

    Derivatives of a Quadratic Function with Step-by-Step Instructions

    no i don't know how to take the derivative of a polynomial? is that? let me try though. first i expand this two terms: i ended with some cubes nd quartics then i took the derivative.(when u multiply the exponent with coffiencent and the subtract the exponent with 1) thats wehre i get...

    Derivatives of a Quadratic Function with Step-by-Step Instructions

    Hi I need help with the Derivites please. Find the value of dy/dx for the given value of x. y= (3-2x-x^2) (x^2+x-2), x=-2 I have tried that I can't seem to understand the real steps to get the answer. I know I have to take the deriviate of this actual function... once i do that..I...
