Use graphing technology to write equations for polynomial functions whose graphs have
the characteristics listed when plotted on the coordinate plane.
1. A 1st degree polynomial function whose graph intercepts the vertical axis at 8.
2. A 2nd degree polynomial function whose graph has only positive y-values.
3. A 2nd degree polynomial function whose graph contains the point (0,-9).
4. A 3rd degree polynomial function whose graph crosses the horizontal axis more than
once.
5. A 4th degree or higher polynomial function whose graph never crosses the horizontal
axis.
