I'm new to the forum. I'm a 21 year old college student trying to become a high school math teacher. School's been going as planned so far, but these proof based math classes are extremely difficult for me and I need help like no other. Right now I'm taking Intro to Real Analysis. Next semester I'll be taking Advanced Algebra, and Discrete, then hopefully I'll be student teaching the following semester.

I came here for help, like most, so I could really use it.

I already posted a question I had for my homework, I am lost and in dire need of help.

It's under the applied math section I think.
