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
