A line about which a figure is symmetric is the _____________________.

• Solution Set

• Intercept Formula

• Quadratic Function

• Axis of Symmetry

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

​

• x

• -2

• y

• -3

• -1

• 1.5

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
