Mr. Contreras does an excellent job explaining the concept of maximum and minimuns and how they are they determined. The example of the rollercoaster was a great visual to understand parabolas and how they work. It might be nice if the the videos were combined, that way it's all together on one.

Mr. Contreras has a nice opening and engages his viewers with the rollercoaster giving a real life example of a parabola. I feel that the material covered in the video was a little too limited. It would have been nice if he included more to the concept of parabolas. I like that he draws the parabola to show the concept of a minimum.

I like that Mr. Contreras had a picture of a rollercoaster at the beginning and then showed its shape on the graph. This is hlpful in seeing the real world applications of parabolas. I think it would be nice, but not necessary, to show other steps along with this video. It's simplicity makes it easy to follow, but it seems like there could be more included.
