In this video we will talk about the importance of functions and their application. We start by reviewing previous concepts such as the relationship, then we define the function and finally we build the graph of some common functions. To finish, we highlight the importance of functions and their application in the modeling of many phenomena and their connection with various areas. The creation of these videos takes me quite a bit of time.

Personally, I find it a very useful tool to better explain many concepts in a visual way. If you are interested, here is the link to the Manim library for Python: https://github.com/3b1b/manim Without further ado, thank you for your attention and see you in the next video
