the vertex is a maximum turning point We can identify these properties from a quadratics graph or equation.

This is an interesting class of functions, but not nearly interesting enough for calculus purposes. While I do spend lots of time pushing the idea of linear approximations on my students ...

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of \(y = x^2 – 6x + 4\) The coefficient of \(x^2\) is positive, so the graph will be a positive U ...
