In this part you do not have to sketch the graph and ... 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 ...

A quadratic equation ... 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, x = 0, x = 1 and x = 2.
