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 ...
But if they did, they apparently forgot to share it with anyone in any permanent form ... called a reduced quadratic equation. However, it doesn’t look like anyone put all the pieces together ...
The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form. Find the equation of the line of symmetry ...
