Why are Conic Sections given this name?

• They are the cross-sections given when a cone is sliced.
• Because it's part of 'da rules'
• They are the cross-sections given when any 3D image is sliced.

In the equation (x-3)²+(y+4)²=121, the radius of the circle is

• 242

x + 3 = (y  - 1)²

• Parabola Opens Up
• Parabola Opens Down
• Parabola Opens Right
• Parabola Opens Left
