9. Through investigation using Computer Algebra Systems, divide the polynomial function by (x - a) for various integral values of a using (k). Compare the remainder from each division with f (a) (k,t).(C3.1) (2points) 10. Solve the inequalities function f (x) > 0 by graphing (using Fathom, Spreadsheet or Graphing Calculator) and evaluating the corresponding function, and calculate the intervals for the x. Write down the results on a number line and algebraically. (k,t.a)(C4.2, 4.3)(2 points)
