Therefore the coordinates of the turning point are (-1, 2). If we recall the general equation: \(y = a{x^2} + bx + c\) then if: a > 0, then the shape of the parabola is like a happy face and the ...

So aim to be able to recognise the equations and graphs of quadratics, cubics ... 9\) so the graph crosses the \(y\)-axis at \(y = 9\). Sketching a quadratic using the turning point and the ...
