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

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