I'm in calculus, but we're having this test on some curve sketing soon and I'm doing some practice problems that the teacher gave us. We're not allowed to use a calculator in this calculus class (except for very rare instances) so we have to know how to sketch graphs with no problem! I'm wondering I have factored this correctly. If not, I'm wondering if someone can point me in the right direction. Orginal Equation: [tex] x^3 - 3x^2-6x+8 [/tex] My Factors [tex] (x+2)(x^2-2x+4) - 3x(x+2) [/tex] Turns into ... [tex] (1-3x)(x+2)(x^2 -2x + 4) [/tex] If anyone could help me out I would appreciate it. Thanks!
