ahh it cleared up what others vids didnt describe :) that domains of functions can be described as constraints that the function can't be - and its easier to express it as "x cant equal this" so that is what we're solving for my mathematical reasoning is not present qwq
@@thoughty2fan278 for rational function, equate the denominator to ≠0. so x can take any number except 2. the domain will be (-∞,2) or (2,∞). for function with sqrt, equate it to ≥0 (but without the sqrt). the answer will be (7,∞) since x can take any number.
This guy is incredible, struggling all day, watching other videos, I watch this 4 minute vid and now everything makes sense
Online education ftw :)
If you need some more practice, you might benefit from one of my videos on math/physics :)
On god
This guy did better in 4 minutes than my teacher in two weeks
love this he uses common sense to explain not any complicated words love this pls do more of these.

thank you for helping me to understand this hours of confusion solved in a 4 minute video 😭😭
hehehe
Wow! Powerful video. I think I have got A+ in further calculus ❤
Life saving videos. Thanks you so much
I haven't been in highschool in a year, but my friend showed me this, I don't get it, I guess I'm all washed up now.
a function has a domain per definition.example f: N\{0} --> R , z |--> 1/z
now it makes sense. Thank you !!!
So , Co-domain can include imaginary numbers and infinity?
(For negative number under the radical it can give a possible outcome)
such a good video I kiss your heart
I still dont understand current doing BA degree MAC 1105.....
I’m in high school with this
perfect
Good video
What does it mean if D:{-2,-1,0,1,3}
That’s when the line is on the x axis
Mmmm, not totally clear…
Can you explain it in a simpler way for me then please (I’m being genuine not sarcastic)
