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

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