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 ...

(If a were zero, you would have a linear equation.) Through this equation, you can identify the vertex, axis of symmetry and the direction in which the parabola opens. Follow these steps to draw a ...
