Best ResponseYou've already chosen the best response.0These are quadratic functions. They are of the form\[y=ax ^{2}+bx+c\]Axes of symmetry for quadratic function are always vertical lines. The equation of the axis of symmetry is determined using\[x=\frac{ b }{ 2a }\]For each of the given functions, use the above formula to determine the equation of the axis of symmetry and then arrange them in ascending order.

Best ResponseYou've already chosen the best response.0For example, if you are given\[d \left( x \right)=4x ^{2}3x2\]the axis of symmetry would be\[x=\frac{ \left( 3 \right) }{ 2\left( 4 \right) }=\frac{ 3 }{ 8 }\]Get the idea?
