Module 4 Evidence

To practice for the modular exam, I decided to do some of the book's exercises, in which I made the procedure and gave a result, which I compared to the book's answers, many of them turn to be correct, but some of them turn out to be wrong, in order to see what I got wrong I did the exercise again, but to understand why the answer was what is was, I use the tool of geogebra to see the behaviour and answers of the problems, from there on I have use this tool to make graphs that make me understand the reason why the graphs behave the way they do.
