2. polynomial functions: we modeled many things in chapters 1 - 3 with linear functions. in
reality, we can model many situations more accurately using polynomial functions. in a
polynomial function, the expression that defines the function is a polynomial.
example 2: let p(x) = 2x2 - 3x +1. find:
(a) p(0) (6) p(-1) (c) p(m) (d) p(-31).
