I have a graphing problem I need help with please
Quuestion: https://imgur.com/a/uzKVvfA
h, or x-coordinate of vertex occurs where
k, or y-coordinate of vertex:
With (h, k) being (- 6, 4), we get: ============
| x y |
|- 10 |
|- 8 |
|- 6 - 4 |
|- 4 |
|- 2 |
============
Populating the y-slots above or below the vertex,
(- 6, - 4) gives us: ============
| x y |
|- 10 12 |
|- 8 0 |
|- 6 - 4 |
|- 4 |
|- 2 |
Below the VERTEX, we have the SAME y-coordinates
we just found, ABOVE. This gives us:============
| x y |
|- 10 12 |
|- 8 0 |
|- 6 - 4 |
|- 4 0 |
|- 2 12 |
============
You now have the vertex, (- 6, - 4), plus 2 points on EITHER side of the vertex.
In addition, if you look you'll see the solutions to the quadratic: the points on the x-axis, or the roots,
which are: - 8, from point (- 8, 0), and - 4, from the point, (- 4, 0)
