How to draw the graphs 𝒚 = 𝒙² and 𝒚 = -𝒙² There are no straight-line segments on a quadratic graph. The coordinates \ ( (x, y)\) are plotted and joined by drawing a freehand curve.

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function y = a x 2 + b x + c is a smooth curve with one turning point.
