Answer:

1. So, I think the similarities among the given pictures are there shape(s) and style(s).

2. It is a quadratic function. Because, as you can see the shape(s) in each pictures are forming a parabola, a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

3. The connection of this to our topic is that the shapes being formed in the pictures.

4. I think the main focus of this is that using a cartesian plane we'll be forming shape(s) like what could be seen in the pictures.
