Examples finding the domain of functions

[@Oogabooga-]

This guy is incredible, struggling all day, watching other videos, I watch this 4 minute vid and now everything makes sense

[@PenandPaperScience]

Online education ftw :) If you need some more practice, you might benefit from one of my videos on math/physics :)

On god

[@ferdzpubg5672]

This guy did better in 4 minutes than my teacher in two weeks

[@bigpanda9437]

love this he uses common sense to explain not any complicated words love this pls do more of these.

[@MaxScince]

Life saving videos. Thanks you so much

[@unshibe]

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

[@GodwinKorkuDorborkoe]

Wow! Powerful video. I think I have got A+ in further calculus ❤

[@princess9354]

thank you for helping me to understand this hours of confusion solved in a 4 minute video 😭😭

[@redsword7192]

hehehe

[@jihenebenarab6754]

now it makes sense. Thank you !!!

[@berndmayer3984]

a function has a domain per definition.example f: N\{0} --> R , z |--> 1/z

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.

such a good video I kiss your heart

[@TalalKarim-l3b]

So , Co-domain can include imaginary numbers and infinity? (For negative number under the radical it can give a possible outcome)

[@DeeJayFuego]

I still dont understand current doing BA degree MAC 1105.....

[@carlosruiz2956]

I’m in high school with this

[@kompelisibeso5429]

perfect

[@byebyebabi]

Good video

[@iafedaleman4881]

What does it mean if D:{-2,-1,0,1,3}

[@BeanMinecraftforlife]

That’s when the line is on the x axis

[@aaronhall7988]

Mmmm, not totally clear…

[@thoughty2fan278]

Can you explain it in a simpler way for me then please (I’m being genuine not sarcastic)

[@hab33bahbh69]

​@@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.
