Introduction to Inverse Functions

Beautiful, clear and straight forward class

so confusing about how you explain to test the graph using vertical and horizontal line you said used a vertical line for the original function and horizontal line for inverse function ???????

Rosalynn Carter died. :(

Who’s studying for their test next period 😅

I literally studied this for hours just for this man to get me to understand it easily after one example problem

this man = jesus.

i think the first question is wrong. how is 3y-1 multiplied by x equals to 3xy-3x. i understand the 3xy part but how did the 3x happen? there is no 3 to multiply it with ? or maybe i am trippin

straight schlompin vid dude

i wish all the best for you man thank you so much for your great videos!!

You sir have saved my back and if you are ever in need of help just say something because after watching your videos all hope is not lost and I might just pass math.

What is domain and range I don't understand it

Thank youuuuuuuuuuuuuuuuuu

THANK THE LORDS AHSGAIAHA I HAVE AN EXAME TMR AND IM DYING 😭😭😭😭

my brain burn out😅😢

Whos studying while reading the comments 😂😂😂😂😂

Math is everywhere

bro ur the best wallahi

tyyy

1. how to find inverse function
2. how to know if 2 functions are inverse function of each other
3. the property of inverse function
4. how to draw the inverse function
5. how to know f(x) is a function?
6. how to know the inverse is a function

All of your videos are so simple and easy. I normally don't comment, but your videos have been so helpful while I prepare to take calculus this semester. Compared to professor's videos and other resources, you just make learning so clear. Thanks for all your videos.

I am 69 years old and I am watching this just for entertainment

could you please make a playlist for only the function from the introduction to the last topic

You explain things clearly, but some of your examples are wrong. f(x) = x^2 - 4 is not a 1-1 function, therefore has no inverse. You should have noticed this when you took the square root of y^2 which gives two answers. If you limit the domain of f(x) = x^2 - 4 to [0, infinite) then it has an inverse.

you are my literal savior omg 😭

Telugu lo

these are so usefull last term i passed for y9 to y10 cause of this channel
3 day of this channel = 90+
in math

Didn’t go to class for 2 weeks and I have a test today. I’ve been watching his videos for 3 hours, let’s see how much I get on my test just from watching😂😂😂

I took precalculus in 9th grade and I had a 68 percent, Then I watched this video and others about precalculus in your channel, I graduated the top of my class and I now made it to the university of Florida. Thanks for your help, this video is awesome.

Your voice calms my math anxiety 😢

Playing this at X2 speed, and I still understood it better than some teachers teach for 2hrs

your the best tutor🎉

ze brain is not functioning well

I will be writing exam in 3 hours time and this video has really helped me in terms of my preparatory..Thank you

In just one minute, he makes me understand what my teacher has been failing to get thru to me for a week. Just one minute omg. I love you. 😭

Watching this right before my Math finals

thanks pro continuse

you are saving my ass, my guy. TYSM!!

You are the best tutor ❤

Te amo

But you got two outputs for y. I thought it's not a true inverse if that's the case. Don't you have to restrict the domain? Otherwise it doesn't pass the horizontal line test.

Thank you so much !

Help got a test in 5 min
