Polynomial Equations and Root Graphs #1


Question Group #1
Directions and/or Common Information: Solve for the roots of each function f(x) and then graph.


f(x) = -24x3 + 60x2 + 48x - 36
1. 





f(x) = -2x2 - 16x - 24
2. 





f(x) = 0
3. 





f(x) = -x4 - 2x3 + 63x2- 36x - 324
4. 





f(x) = x3 + x2 - 8x -12
5. 





f(x) = 2x3 + 16x2+ 22x - 40
6. 





f(x) = x4 + 3x3 - 18x2
7. 




Question Group #2
Directions and/or Common Information: Using the graph, list all possible roots of the curve and give an equation.
