INTRODUCTORY EXERCISES

(1) If p(x) = 4 - 3x + 1/2x2, then find:
    (a) p(1)
    (b) p(1/3)
    (c) p(-)

    (a) p(1) = 4 - 3(1) + 1/2(1)2
             = 4 - 3 + 1/2
             = 11/2    

    (b) p(1/3) = 4 - 3(1/3) + 1/2(1/3)2
               = 4 - 1 + 1/2(1/9)
               = 3 + 1/18
               = 31/18

    (c) p(-) = 4 - 3(-) + 1/2(-)2
              = 4 + 3 + 1/22
