Through this equation, you can identify the vertex, axis of symmetry and the direction in which the parabola opens. Follow these steps to draw a parabola with the given equation: y = 2 2 − 4x ...

y = x² + 6 - moves the parabola 6 places up the y axis y = x² – 7 - moves the parabola 7 places down the y axis In the video, the 2D curve of the Lovell Telescope dish is a parabola.
