Answer 1

It looks like you have provided solutions for practice problems related to graphs of quadratic equations and a quick check for the same concepts. If you would like to review or verify these answers, or if you have specific questions or need further explanation on any of the concepts, feel free to ask!

Here's a quick summary of the terms involved in quadratic equations that you've mentioned:

1. **Vertex**: The highest or lowest point of a parabola, depending on whether it opens upwards or downwards.
2. **Axis of Symmetry**: A vertical line that runs through the vertex, dividing the parabola into two mirror images.
3. **Y-intercept**: The point where the graph intersects the y-axis.
