Quadratics
6.2 The Full Power of Symmetry
Lesson materials located below the video overview.
SETTING THE SCENE
Through the power of symmetry we’ve started graphing quadratic equations with ease. We noticed, for instance, that for
\(y=\left(x-3\right)\left(x-7\right)+10\)
the \(x\) values \(3\) and \(7\) are interesting and led us to two symmetric points on the symmetric curve. Then common sense allowed us to swiftly sketch the equation’s graph.
And for \(y=x\left(x-4\right)+7\) the values \(0\) and \(4\) are interesting.
But most quadratic equations are presented in a different, namely, in the form
\(y=ax^2+bx+c\).
Is there a way to identify interesting values in such equations?
