9.2 Parabolas

Emerald Seing


A parabola is defined in terms of a fixed point, the focus, and a fixed line, the directrix. PF=PD meaning that any point on the parabola to the focus is equal to the shortest distance from that point to the directrix.




Horizontal Directrix

  • The parabola will open either up or down

  • The equation will have Y by itself on one side

  • The line of the directrix will cross the Y-axis

  • The axis of symmetry will be on the Y-axis

  • Y=…

Vertical Directrix

  • The parabola will open either right or left

  • The equation will have X by itself on one side

  • The line of the directrix will cross the X-axis

  • The line of symmertry will be on the X-axis

  • X=…
