I apologize if these are starting to become annoying. I'd like to know if these notes I've written on what functions are so far are correct. I'm aware they might get repetitive in some places, but what I mainly want to know is if they're correct/adequate enough explanations. I mostly took what I wrote down from mathisfun and a bit from what @jsreed5 told me. (I'm not writing this to show to anyone, I just write notes I take as if I'm writing a lesson for myself.) This is a longer one. In…

I have another question, yet again. I'm learning about independent and dependent variables. Is this explanation I wrote for myself correct? I haven't written it in my note book yet so I can still change and add to it without much trouble if I need to. An independent variable is a variable that can be manipulated to give us the value of the dependent variable. A dependent variable is a variable that has a value that can only be found by substituting the independent variable for something. For...

Is there any particular reason why exponentiated negative numbers must be in parentheses like this: (-2)³ instead of being written like -2³? I looked around for a little bit and so far it seems like it's to show that it specifically shows that it's the result of negative 2 multiplying itself 3 times and not specifically the negative version of 2³. Is it to clear up ambiguity, like making sure you'd realize (-2)⁴ is 16 and not a round about way of saying negative 16 like -2⁴ might be interpreted...

Alright, one more question. Yes, I know this says precalculus, but I was looking at this video: [https link] and understood everything except for why the middle factor at 7:15 has a power of 1. Is it because of the variable's implied power of 1, or because any term/factor in math that doesn't show an exponent has an implied power of 1 like lone variables? Thanks to wonderful SEO searching for this only brought up basic exponent rules, and I had to end up asking a couple of LLMs that said so,...

I have another math question, and it's if this introduction to polynomials I wrote for myself is any good. The things in parentheses like (positive whole numbers) are for later if I come back to do a quick read-through given my less than stellar memory. A polynomial (from the Greek word poly, meaning many, and the Latin nomial, meaning names or terms) is an algebraic expression which consists of variables (also referred to as indeterminates) and coefficients that only involves the operations...

In an expression like 2 · 3 + 4 - 7y, would 4 count as being a term that has exactly one factor since nothing is being multiplied in it? I ask because trying to figure this out I looked at a video on Khan Academy going over terms, factors, and coefficients and they said 4 would only have one factor. I've also heard that an expression with just multiplication counts as one term. Edit: I just thought about the other definition of factor. Is the term considered to have one factor because the...

Rug Coloring — This is a neat little recently discovered unsolved puzzle about rug coloration. I wrote a little piece of code to generate pictures of the rug diagrams.
