Graph of a parabola formula

Webon the directrix is the difference of the y -values: d = y + p. The distance from the focus (0, p) to the point (x, y) is also equal to d and can be expressed using the distance formula. d = √(x − 0)2 + (y − p)2 = √x2 + (y − p)2. Set the two expressions for d equal to each other and solve for y to derive the equation of the parabola. WebExample 3 Graph of parabola given three points Find the equation of the parabola whose graph is shown below. Solution to Example 3 The equation of a parabola with vertical axis may be written as \( y = a x^2 + b x + c \) Three points on the given graph of the parabola have coordinates \( (-1,3), (0,-2) \) and \( (2,6) \).
