Parable Equations


Let's consider the following cases:

A) Parabola with origin vertex, right concavity and horizontal symmetry axis

Like the straight line d have equation and in the parable we have:

  • ;

  • P (x, y);

  • dFederal Police = dPd (definition);

We then get the equation of the parable:

y2 = 2px

B) Parabola with origin vertex, left concavity and horizontal symmetry axis

Under these conditions, the parable equation is:

y2 = -2px

C) parabola with vertex in origin, upward concavity and axis of vertical symmetry

x2= 2py

D) parabola with vertex in origin, downward concavity and axis of vertical symmetry

x2= - 2py
