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

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