Sketch the graph of \(y = x^2 – 2x – 3\), labelling the points of intersection and the turning point. Show answer Hide answer The coefficient of \(x^2\) is positive, so the graph will be a ...

The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) and a maximum turning point when a \(a \textless 0 \). The turning point lies on ...
