1. y = 4x2
Skinnier and up
3. y = x2 + 4
Up 4 on y-axis and opens up
5. y = 2(x - 5 )2 + 3
Skinnier, opens up, moves right 5
on x-axis, and up 3 on y-axis
2. y = 0.5 x2
Fatter and up
4. y = (x + 3)2
opens up moves left 3 units
6. y = -0.4( X + 2)2 - 6
Fatter, opens down, left 2 on
x-axis, down 6 on y-axis
