The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression ... of \(y = x^2 – 6x + 4\) The coefficient of \(x^2\) is positive ...

Rewrite \(y = {x^2} - 6x + 11\) in the form \(y = a{(x - b)^2} + c\). In this case \(a = 1\) as the coefficient of \({x^2}\) is \(1\). To get the number inside the ...
