There are 3 points shown lie on the graph of a quadratic function. Which of the following is the line of symmetry for the quadratic function?

​ (a)   = ​ (b)  

Hint: AOS, is x = # , anytime you are given points, use stat, so it is a quadratic ,therefore use quad reg, and then once you get that, use testing desmos and the axis of symmetry is where the graph gets cut in half perfectly

This vertical green dotted line is called the "Axis of Symmetry" because...

• It is the place where the parabola is the same (a mirror image) on both sides

• It crosses the x-axis

• It is a vertical line
