If y=x2, then (0,0) is the centre.
If 4a(y-k)=(x-h)2, then (h,k) is the centre, where a is the focal length.

yes
u look at it.... :-) hey I'm learning about parabolas too
The vertex of this parabola is at -3 -1 When the y-value is 0 the x-value is 4. The coefficient of the squared term in the parabolas equation is 7
Go study
One career that might use a parabola is a mathematics teacher. Geometry teachers might also use parabolas. A parabola is a line consisting of points that are connected and spaced unilaterally.
Any and all conics, parabolas included, take the form Ax2 + Bxy + Cy2 + Dx + Ey + F = 0, with A, B, and C not all zero. The parabolas themselves have B2 - 4AC = 0.

Functions (lines, parabolas, etc.) whose graphs never intersect each other.

If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
