PARABOLA

The graphs of quadratic functions are called parabolas

Directrix - A parabola is the set of all points equidistant

from a fixed lineFocus- Fixed point not on the line

ELIPS

An ellipse is all points found by keeping the sum of the distances from two points (each of which is called a focus of the ellipse) constant

Cara melukis graf elips

• Kenal pasti 4 titik utama- Right point (h+a,k)- Left point (h-a,k)- Top point (h,k+b)- Bottom point (h,k-b)• Kemudian sambung semua titik tersebut
