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 ...

A quadratic equation is drawn as a curve on a set of ... We can use these values to find the values of y for the graph. Step 4 – Repeat this process for the remaining values, where x = -1 ...
