EXAMPLE 1: QUADRATIC OPENING DOWNWARD Write the simplest form of the function given by the graph: From x = (-4) --> (x+4); From x = 2--> (x-2) |
EXAMPLE 2: POLYNOMIAL OF DEGREE 5
The x intercepts are (-4), (-2) and (1). From x = (-4) the factor is (x+4). From x = (-2) the factor is (x+2). From x = (1) the factor is (x-1). The function is the product (x+4)(x+2)(x-1). |

Concept Check: Given that the zeros of a function are x = 0, x = 6 and x = (-3), write the simplest form of the function.
