Advanced Functions Chapter 3 Portfolio Assignment(page 2) Factor f (x) = 21x5 - 89x4 +44x3 + 112x2 - 120x + 32 fully, i.e. write fin factored form. Demonstrate a full understanding of the content of this unit, (i.e. do not simply type the equation into a graphing calculator-be sure to demonstrate all of your analytical skills-analytically unsupported conclusions are not worth marks). Student's work demonstrates understanding of the: a) [1 ]remainder theorem to inform where the roots are b) [1 ]leading co-efficient and constant to inform rational root choices C) [1 ]the factor theorem to confirm roots d) [1 ]long division algorithm e) [1 ]synthetic division algorithm [1 ]quadratic formula
