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 + 1 In this case ...

For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following diagram shows the main properties: If k > 0, the vertex is a minimum turning point If k < 0, the vertex is a maximum ...
