Quadratic Graphs You need to know how to plot graphs of quadratic equations

Quadratic Graphs Plot a graph of the equation ‘y = x x2x x y

Quadratic Graphs Plot a graph of the equation ‘y = x 2 + 2x y x x2x x

Quadratic Graphs Plot a graph of the equation ‘y = x 2 - x y x x2x x

Quadratic Graphs Plot a graph of the equation ‘y = 3 – x x2x x

Summary We have looked at plotting graphs of quadratic equations They will always be a curve, either an ‘n’ or a ‘u’ shape
