We can’t change function notation, but maybe we can commit to color coding functions on introduction?

How do you use color coding?

I was just going to ask the same question! 😀

Often on the board, I think of the input as what to color code. Example back of the envelope photo since I am not at work right now.

Yes. Might leave the () black.

I’ve thought about that, and quite often students substitute without parentheses as a mistake, and when it comes to negative signs or composite functions or transformations this leads to errors. So as an introduction, I would highlight the parentheses as well.

I like this! I think I’ve done something similar in the past without even realizing it. I like using multiple colors on the board when writing.

Nice! I'm a big fan of color coding. I think this concept is also tricky for Ss cuz they think of f as a variable.
