How to find the inverse of a rational function and verify it's inverse

👉 Learn how to find the inverse of a linear function. A linear function is a function whose highest exponent in the variable(s) is 1. The inverse of a function is a function that reverses the "effect" of the original function. One important property of the inverse of a function is that when the inverse of a function is made the argument (input) of a function, the result is x.

Given a function, say f(x), to find the inverse of the function, we first change f(x) to y. Next, we change all x to y and y to x. and then we solve for y. The obtained solution for y is the inverse of the original function.

why are people talking over this dude? i would love to have a teacher like this :/

[jaym]

ty. like how u teach and shut the students up at the same damn time

[chrunchyz]

I've been scratching my head for a whole day just by trying to understand my math homework, this video really helped me. Thanks good sir

[Henry-jqhc]

Ty so much, last minute studying for test

[brianmclogan]

I absolutely agree. Cancelling out is not a mathematical term nor should it be used when describing the process of a number being added to it's multiplicative inverse or multiplied by it's multiplicative inverse. I sometimes fall victim to using the term but always try to explain like you do during lecture. Thank you for noticing and writing to me about it because I agree with you

[BiiKay]

Sir this is all I needed to understand inverse function. As an English speaker, I'm studying maths in Chinese and you just saved my life. Your students are so lucky to have you. You're the best man!

[brianmclogan]

Thank you please feel free to ask any questions, I will try my best to answer

[datoland]

I am currently using webassign for my college algebra, and your explanation is 10x better than the random people that "try" to explain how to do these.

[otb.ger]

Man those students are super disrespectful for talking while hes teaching🙄 They should be grateful they have a teacher that actually teaches while some of us WISH our teacher actually taught well🤦🏻‍♀️ Great video btw thank you so much

[brianmclogan]

@DevPosley awesome, let me know how I can help you further!

[jennaalexander]

What if the 5 was the numerator and x-1 was the denomenator. Would you multiply by (1/5) to get rid of the 5?

[brianmclogan]

please do and let me know what videos you would like to see that you don't see on my channel

[luzgarcialara]

Just wanted to thank you so much for this! currently doing college algebra and I can't tell you how difficult textbooks make it seem.

[TheCstotko]

YES! We're working on this now. I was hoping you had a video up with this information! Brian Strikes Again!

[charleschanda]

So what other methods can I use apart from canciling out the variables

[brianmclogan]

I know right? I goal is to create enough videos to supplement all the long boring instruction out there. It can just be killer here in math class.

[faithsollearns]

I'm struggling to understand how 5 got cancelled out in "5x=y-1" just by adding 1, how does it work?

[romeobluepadres]

Thanks Mr. McLogan, the book was confusing!!! This helped

[xxxMellowRebelxxx]

How do you work the problem with something like x-5 on the bottom?

[lykzjrmaf]

You just make it very simple.... Thanks a lot...
