Ms. Duina Zeineddine explains how to write the equation of a
rational function and graph it. Concepts include domain and range
and asymptotes as limits. Questions this video answers How to write
the equation of a function from given data? What does the graph of
this function look like given the domain and range of the function?

Ms. Zeineddine does a great job explaining the equations she sets up from the word problem. She uses new variables when necessary and describes why she is setting up the equation the way she is. Even she sets it up clearly, I feel like a deeper explanation or slowing down would be helpful. I love that she graphs the equation for a really strong visual. Also, that she takes the time to explain number of shirts is our x-axis and domain, cost of shirts is our y-axis and range.

I like that Ms. Zeineddine shows a real world example of a rational functions. It would be helpful if she talked a little bit about what a rational function is before she started the problem, especially because she never refers to any function as a rational function during the video.
