Identifying Parts of a Parabola

Identifying Parts of a Parabola

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 x=-\frac{3}{2}=-1.5. Since the parabola is facing up the y-coordinate of the vertex represent a minimum value. The vertex is ( \frac{3}{2}, \frac{5}{2} ). The minimum value is \frac{5}{2}.
Point A is ( -\frac{5}{2}, \frac{9}{2} )= (-2.5,4.5) and its corresponding point would be ( -\frac{1}{2}, \frac{9}{2} )= (-0.5, 4.5).
Point B is (0, 7) and its corresponding point would be (-3, 7).
