Given f(x)=3x + 1, Let’s find the INVERSE FUNCTION step-by-step….

15 minutes in until he actually teaches us. nice

[@faye4778]

Great work and simple explanation, however you repeat yourself a little bit and tend to deviate from your explanation, making the topic longer that needed. This should be a 10 minute video. Thanks for posting.

[@troybush5899]

What's a "function" and its "inverse"? Where and why is this stuff used in the real world? Please give a few examples...it would make math more palatable.

[@createlyrics7413]

Thank you for teaching us☺

[@KookyPiranha]

Lmao i was wondering this entire video what f^-2(x) would look like

[@robertstack2144]

Gabby, I'd hate to have you explain 1+1=2

[@gavindoughty6374]

test is in 20 mins am i cooked?

[@Kathrine3197]

omg he just talk n talk

[@petereziagor4604]

I'm for sure glueing to this channel now. Awful I've been solving function inverse without actually knowing the full details of what I'm solving, the domain and the range,.

Hi John, for years I have struggled with math, but never got the knock of it, I am now holding out on you. The thing is, I do not have a computer nor a laptop. Can the course be done on my mobile phone. I await your reply.

f^--(x) =x--1/ 3

[@lorenzocole8166]

I could have used this video anytime before last Wednesday on 12/15/21 for math final.

[@petereziagor4604]

I don't take notes but I do understand almost everything I watch here on KZbin Makes sense if I should start taking notes

[@hannahbishop7020]

John, you are a patient teacher and very good at your job. I notice you do a lot of sketches of faces, perhaps there is an artist waiting in the wings.

[@danielmadden9691]

y=x-1/3

[@danielmadden9691]

I have seen your steps John in a similar example, well explained

[@antistress-2]

thanks!

[@praveengill113]

I want to sign up for your class, please advise

i've always hated this notation and terminology. Calling this inversion and using exponential notation for inversion when it's actually something very different is unnecessarily confising. I believe there was even a cursed math meme involving inverse and exponential trigonometric functions and the way various solvers like wolframalpha interpret them. In CS we talk about the reversibility of a function which is a better term but the exponential notation is the bigger problem.

[@thalanoth]

keep in mind prime notation is written with apostrophe-esque marks, not a 1, as in raised to the first power. First derivative is n', not n^1. Second derivative is n'' not n^11 lol. Lots of different notations, but hard to see difference when being hastily handwritten, especially electronically lol

[@protocol6]

@@thalanoth Yes. I'm not fond of either of the parenthetical notations for the rice crispies derivatives, either. It's potentially three different meanings for parenthesis in the same equation with nothing to distinguish them.

@@protocol6 aw snap hahahaha

[@brothercaleb]

Longwinded and confusing
