Definitions:
0. y= -4 - 10x %2b 8x^2
1. y = -4x%2b10x - 8x^2
2. Quadratic Function
3. y= -8x - 4x^2 %2b 10
4. y = 10x ^ 2 -8x %2b 4
5. y = -10x %2b 8 %2b4x^2
6. axis of symmetry
7. y= -8x^2 - 4x %2b 10
8. y = -4x^2 -10 - 8x
9. y = -8x%2b10 %2b 4x^2
10. y= 8x^2 %2b 4x -10
11. y = 10x %2b 4x ^2 - 8
12. roots
13. y = 8x - 10x^2 %2b 4
14. y= -10x^2 - 8x - 4
15. Vertex

Answers:
0. a= -10 b = 8 c = 4 opens down
1. a=-4 b=-8 c=10 opens down
2. minimum or maximum
3. zeros solutions x-intercepts
4. a= 4 b= 10 c= -8 opens up
5. a= 4 b= -8 c= 10 opens up
6. a= 8 b= -10 c= -4 opens up
7. line cutting graph into two equal parts, goes through vertex
8. a= 10 b= -8 c= 4 opens up
9. u-shaped degree of 2 parabola
10. a=8 b=4 c=-10 opens up
11. a = -8 b = -4 c=10 opens down
12. a= -10 b = -8 c= -4 opens down
13. a= 4 b= -10 c= 8 opens up
14. a=-4 b= -8 c= -10 opens down
15. a=-8 b=-4 c=10 opens down
