Example 3 Understanding the Graph of Parabola For you to do.
For the figure, identify the axis of symmetry, the vertex, the minimum or maximum value and explain why it is a min or a max value, identify both points and their mirror image about the AOS.
The axis of symmetry is . Since the parabola is facing up the y-coordinate of the vertex represent a minimum value. The vertex is . The minimum value is .
Point A is and its corresponding point would be
Point B is and its corresponding point would be
