Document Summary

Provide a generalization to each of the key terms listed in this section. Identifying polynomial functions f (x) = anxn + an 1xx 1 + + a1x + a0. Graph: horizontal line with c, which can also be b, as y-intercept. Graph: a nonhorizontal and nonvertical line with a slope and y-intercept. Example : y = x2 + 5x + 6. Graph: a parabola with the graph opening up when a2 > 0 and opening down when a2 < 0. Power function f (x) = axn a 6= 0 n > 0. Zero of even multiplicity f (x)"s sign doesn"t change from one side of r to the other side, which will make the graph touch the x-axis at r. Zero of odd multiplicity f (x)"s sign does change from one side of r to the other side, which will make the graph cross the x-axis at r.
