Lesson_SolvingPolyInequalities.notebook 1 October 15, 2009 4.3 Solving Polynomial Inequalities Example #1: Consider the function f(x) = ( x – 3)( x + 5)( x + 2). (a) State the domain and range of f(x) . (b) Find the real zeroes of f(x) . (c) Graph the function. (d) Find the intervals where . Use the zeroes and the domain of the polynomial to determine the intervals where a polynomial function is positive and where it is negative. There is a possible change of sign in a polynomial on either side of a real zero. We can examine the possible sign changes without graphing the
