MD = y p According to the above definition of the parabola these two distances are equal;For 2 y 2 /b 2 = 1;The graph of any quadratic equation y = a x 2 b x c, where a, b, and c are real numbers and a ≠ 0, is called a parabola When graphing parabolas, find the vertex and yintercept If the xintercepts exist, find those as well Also, be sure to find ordered pair solutions on either side of the line of symmetry, x = − b 2 a
In this way you fix at zero the coordinate y of the points you are seekingHence √(x − 0)2 (y − p)2 = y p Square both sides and expand the two sides of the equation x2 y2 − 2py p2 = y2 2py p2 Group like term 4py =But the equation for a parabola can also be written in "vertex form" y = a ( x − h) 2 k In this equation, the vertex of the parabola is the point ( h, k) You can see how this relates to the standard equation by multiplying it out y = a ( x − h) ( x − h) k y = a x 2 − 2 a h x a h 2 k

y = x 2, where x ≠ 0 Here are a few quadratic functions y = x 2 5; You can hopefully imagine what is going to happen now We have a y 2 term , so it means it will be a rotated parabola When x = 2, y = 0 The value of x cannot be less than 2, otherwise when we try to evaluate y we would be trying to find the square root of a negative number Since out numbers are all real numbers, x must be greater than or equal to 2In this case, the equation of the parabola comes out to be y 2 = 4px where the directrix is the verical line x=p and the focus is at (p,0) If p > 0, the parabola "opens to the right" and if p 0 the parabola "opens to the left" The equations we have just established are known as the standard equations of a parabola
