Thank you so much! When I was learning this in class, I was immensely confused. I asked my teacher to clarify me, but I still couldn’t understand. So she kindly showed me this video and now I understand how the vertical line test works!

Good , never ever lie saying that you understand when you dont , keep asking even if you SEEM dumb

Thank you so much, sir, I usually never comment on videos but I am very grateful for this!

[@joikookura1255]

Brilliant! So simple, yet effective. But I really want to know why this shows graphs to be functions or not. What does it mean for a graph to be a function anyway?

[@akhun6046]

Yo
What happened !!!
Did you pass ???

[@davidgarza995]

Merethor Okura the definition for a function is for every one x value there is a y value if any x values repeat than it. Fails the definition of a function if there are the same y value but different x values than it still is a function the line test proves this

[@iliekmathphysics]

The vertical line test contains a vertical line. A vertical line can only go through a single x-value, but the vertical line also goes through every possible y-value! If an x-value of a point has exactly one y-value, then the vertical line will pass through only that point. But if the x-value of the point has, let’s say 3 y-values, then the vertical line will go through those three points. Keep in mind, the three points haves the same x-value, and the vertical line can only have one x-value. (Hence, a vertical line can be named as an x-value, such as x=3 or x=4)

[@RougeEminence]

Functions by definition can only provide a single output. If there are two different positions corresponding to a single X input, it means it is not a function, it means that the Y at that point is undefined. The vertical line test basically just tells you whether or not its a function by discerning whether or not there is one or more outputs, but it helps visualize it.

Woah I'm back again to study for the finals. Thanks you're such a great help. I pretty much learn from you than our professor. THANK YOU AGAIN, I OWE YOU ONE

[@soleen7383]

Thanks so much! I was super confused abt the vertical line test ‘till I watched this video. Really simple explanation yet easy to understand.

[@emiliospowerballer1441]

i watched a couple of your videos and i understand all of semesters material in a day, youre a genius

[@lullucy4358]

Thanks for being more helpful than our math books.

[@oweng.2412]

why thank you kind sir for the informational video about the vertical line test, my mathematics teacher was not able to have me to understand this concept because of its complexity, but now i fully understand how it works due to the simple explanation and examples you have presented.

[@jbrewer4387]

thank you man you saved me before a quick that I have to take tomorrow you're the goat man you can teach more to me in 5 mins than my teacher can in 30

[@davidwilliamson5406]

It is good that you show how to use the vertical line test but what I was really looking for is an explanation on why something may or may not be a function if it passes or fails the test.

[@hanmyothwin6596]

I didn't understand when I studied on my own, but when you teach me, I understand now, you are good at teaching 😘😘😘

[@aweirdo9999]

Thank you, I was confused about how a vertical line would work against the vertical line test.

[@georgesadler7830]

MR. Organic Chemistry Tutor, thank you for a solid analysis and a practical solution of the Vertical Line Test.

[@elliltaokubazion7253]

I swear to God I need to hire you as my tutor..u just the bestttt u explain 10times betterrrr

[@EmpyreanLightASMR]

3:10 you can google this and find so many answers on if this is a function or not. Just to keep it simple:
y = √x is a function so long as that's all you're doing. The minute you convert it to x = y^2, or if you decide you're working with ±√x, you're no longer a function.

Thank you sooooo much for helping a mom who is try to go to university.

*Just one correction needed :-* 2:36
*Y=X its not that graph it's a straight line passing thru origin with a slope of 45° and it's a function* ↗️

[@benjaminclark6762]

This is like the best way to test for Inverse Functions.

[@spambots235]

Things i learned
Vertical line (or upright line)
If it touches two or more line it's not a function of only one it's function

[@sreekumarmenonk7678]

another good example may have been a side by side comparison of (to make it obvio):
y^3=x and y=x^(1/3)

To native German speakers, please give me feedback if the following sentence is correct; for I am learning German.

So, the definition of a function is something on a graph that can pass the vertical line test.

Can you put down the vertical line just where u did or can u put it in other areas

[@joreyeumenda2321]

thank youuuuu!!!

[@maehem4289]

Heyyyy what if there are two points(one is an open circle and one is a closed circle) in the x axis? Is that a function or not?

[@audreymagline6344]

so we can draw the vertical line wherever we want as long as its parallel to the y-axis?

[@sabrinaa1088]

i think so

[@Rasha.Hussein44]

Do we need to memorize these functions ?

[@kaz6151]

simple video. thanx. 2/226 complete

Thx

[@thorbolly6279]

THANK U

[@aryanahire2337]

wait, y=sqrt(x) is not a function, the square root of any number is positive and negative.

[@Crackhog]

The square root function only works on positive numbers and only returns positive numbers. Because both negative numbers and positive numbers become positive when squared, you have to assume that the square root of an unknown variable x is both positive and negative, but if you know the number (Like in a function), the outcome is always a single positive number

[@winterberry3412]

but why is it not function? is it because x can't have more than two y-values?
