given the function f defined by f(x) = 2x^3 -3x^2 -12x + 20. a) find the zeros of f. b) write an equation of the line normal to the graph of f at x=0 c) find the x and y-coordinates of all points on the graph of f where the line tangent to the graph is parallel to the x-axis |

yeah this totally isnt algebra 2, but okay? i didnt learn derivatives in algebra 2, nor did i know what a tangent line was... i'm not saying its extremely hard, but this isnt algebra 2 shit broooo |

This is the beginning of the school year, courses like Calc will do reviews on lessons in Algebra II |

a) There is a zero @ x=2, and x=-2.5 b) For the line, I got y = (1/12)x + 20. which sounds wrong.... but it might be right. c) wat. btw im also in calc right now!! so im studying the same stuff. :}} but i think im kinda bad at it. |

a) you say that f(x) = 0, solve from there. b) That means find slope of that function at x = 0 c) graph can be parallel to x axis when its derivative at that point is 0. Find derivative, say its equal to 0, solve equation. |
