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 turning point ...

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 you’ve ever taken an algebra or physics class, then you’ve met a parabola, the simple curve that can model how a ball flies through the air. The most important part of a parabola is the vertex — ...
