Horizontal Line Test and One to One Functions

how about x cubed

this dude has a video for everything

This much easy😲?

The best,
Thank you! :D!

Great & best teacher for us🔥

🇰🇪 Thank you

No words can express how your explanation is stuck in my mind

MR. Organic Chemistry Tutor, thank you for solid explanation of the Horizontal Line Test and One to One Functions and its impact on inverse Function.

Hello sir
Sinx can't pass the horizontal line test but it inverse exist how

You're the Besttttt♥️♥️♥️♥️

Damn 🙏🏿🤝

sana all naintindihan yung math

Thank You very much

Does it matter where you place the horizontal line at?

Some of those fail the VLT (vertical line test) which would make them not a function at all, correct? (Like the example with the circle)

Thank you Mark Wahlberg

First what is one to one function, I am here for that

Are you a chemist? A mathematician? A physician? You know everything ❤️

nice content. I got 1 comment tho: you shouldnt draw arrows at the end of every line, only to the end of abscissa and ordinate, because the arrow shows that the values increase in that direction. And it is really bad to draw arrows on functions... sorry, had to say it, it is a fundamental mistake. (i know i know, this is not the point of the lecture but still). cheers.

Thanks.

One to one function, onto function, and one to one correspondence??????please

Best maths teacher

Excellent explanation

I appreciate you

it helps me a lot, thanks.

how does dis dude got 2.4 million subscribers and has this many views...? im like confused at dis point

Really simple 10qsss a lot

한국어 자막 줬으면...

كفو والله 👏🏼

Hi alel

Strongly Recommended!

What if the graph passes the horizontal test but fails the vertical test will we have a function or just the inverse ?

Are horizontal lines a one-to-one function or not?

You should do a surjective injective or neither video

One to one is Function
Many to many is Relation
One to many is Relation
Many to one is function

நன்றி நண்பா

thank you so much
شكرا جزيلا لك
çok teşekkür ederim

what does the phrase "one-to-one" refer to?

You are wrong for a function to be invertible it should be both one to one and onto

Thanks this video help me :)

I like Your voice can u marry me 🥰

so if it touches the horizontal line test more than once, not a 1-1? yes, i did watch the video, i just like reassurance cus my college exam is tomorrow and i didnt understand this for quite some time..

Thankssss :))
