Bruh, you have a video for just about every damned thing. your channel has been super helpful. Im an adult student trying to learn algebra again after nearly 20 years and the textbook just isnt cutting it. Luckily, I found your channel to fill in the gaps. Thanks
This man has to have the most helpful RUclips channel every time I need help with something about math he has a video about it without fail and every single time he explains it better than my actually teacher
I've taken all my high-school classes and now I'm taking college math, but a lot of the math is based on my old math. I never understood highschool math and assumed I was the problem, but this video explained something I struggled on so simply and it made me realize maybe I'm not the problem.
That's why math is the worst subject in school, kids. Long, drawn out explanations for things that should only take 2 minutes to explain. They overexplain and overcomplicate everything. I'm assuming Common Core Math has made it even worse.
@@morganmiller7197 - Seriously? He explained clearly the difference between them and their required function. Brackets (square) are for that which is INCLUDED, and parentheses (round) are for that which is NOT included (or excluded)! And the parentheses I just used in the previous sentence are for language and grammar, not math. You need to grow up and understand the real world.
Let you give the answer? The point here was that he was giving you the answer! Brackets (square) are for that which is INCLUDED, and parentheses (round) are for that which is NOT included (or excluded)! Both have a distinct function that you need to understand if you are doing math!
@@abbyk_j -- Yes, I knew that, but I thought the curlies were called that as well. What are the curly ones called then? And the plural form is spelled as "parentheses"--with "es" at the end (not "is").
how about when trying to determine the intervals of increase and decrease or positive and negative intervals...does the same rule apply i’m really confused
1:44 How do I determine whether a point is included or not? Why is -2 a parenthesis when it is clear to see on the graph, and -4 a bracket when it is also clear to see in the graph? Aren't both these points included?

Shout out to Brian. SUPER helpful videos!
I don't know why Math has to make things complicated for even PARENTHESES and Brackets, like just let me give the answer..
I'm with you lol
ikr. Like what's the point of having parentheses AND brackets. Like choose one why do we need both

this actrualy realy helped im in highschool gooing through this and have my test soon. this realy helped me clear up some questions i still had
2 words
Thank You
This dude saved my life
ok so if -2 isnt a point of the line/function(?) then why is it plotted on the graph?
because its easier than putting a closed circle on -1.9999999999999
what if there's curly brackets? i've seen those used before in equations like these, but i have no idea how to format them.
If it’s curly brackets then it’s written in a different format, for example : Domain {x| x>2 , XER }
@@abbyk_j - Aren't curly brackets also called parentheses?
@@dwightropp3014 no, these are parenthesis : ()
With parenthesis the above example would be : (2, infinity)

This video is amazing!! Thank you so much!!!🤩

Depends on your teacher, if they include the end points in the increasing or decreasing line then bracket. If not, then use parenthesis.
Thank you
I have no idea what this teacher said at 0:24. I wish he would enunciate the important bits like that or repeat them sometimes like in Khan Academy.
the value is undefined at -2 because it is a hole so that is why I used a parenthesis
1:44 How do I determine whether a point is included or not? Why is -2 a parenthesis when it is clear to see on the graph, and -4 a bracket when it is also clear to see in the graph? Aren't both these points included?
Is this topic similar to limits?
yes, but did not introduce them yet in my PC class
Brian McLogan it’s all good, I’m learning it in calc 1 this semester and I was just making connections in my head haha.
good for you!!!!! seriously!!!
Why do we graph a point as (x,y) then?
I don't understand how -2 doesn't exist
Thank you daddy 🥵 for explaining!
Daddy but what if you have a restriction that is a greater than or equal to? 😮😮😮
You are the best...
Where are you from 🫶❤️
