I watched so many videos trying to understand this concept, and this is the only one that actually made sense to me. Thanks a ton! :)

Thank you for helping me remember. I used to know, but it has been a long time and I have been studying for a certification test. Your simple step by step instruction helped me refresh my memory!

This is all very informative, very interesting, but my question is what are the applications of functions in real life? In other words, how would functions be used in real life? In what areas? I'm fairly certain these things would be useful in science and business. Examples?
