Finding the inverse of a rational function

👉 Learn how to find the inverse of a rational function. A rational function is a function that has an expression in the numerator and the denominator of the function. 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.

This guy is incredible...He has helped me with trig and calculus multiple times...He is a better teacher than my own!!

[brianmclogan]

happy to help, keep up the hard work!

[prae]

Omg thank you so much. I had to find the inverse of f(x) = 3x/(x-4) in pre-calc, and I really couldn't figure it out. This made a lot of sense. Very clear instructions, love it.

3 years later im really thanking you again for this great work may God bless you

[brianmclogan]

lets go get it, let me know what else I can do to help you out!

[briann_rt]

11 years Later, this is still more than useful... Incredible job, thank you very much 😍✨

I have literally been trying to figure out how to solve a math problem similar to this for two days now. This has been the ONLY video that has helped me figure it out and not made it stressful and confusing. Thank you SO MUCH!

[ayeeebae]

i’m literally a freshman in college in precalc because im a complete dumbass in math and youre literally the only person that actually explains everything well omg

[lunadraws]

Inverse functions rationally was so frustrating but now I understand and I hope it gets easier in the near future

[afterift]

omg this made functions so much easier now. Thanks!

[czaplick]

So helpful, you're easy to follow and I found exactly what I was looking for. Thanks a lot!

[muhammadshaheer]

I have my mathematics exam this coming Monday and the syllabus is way too much. I really needed help in finding the inverse of a function and your video helped me a lot! Thank you so much ❤️

I remember my High school math teacher telling me that its not his fault that we dont know what we needed to know to be prepared for his class. He said he will teach what he is paid to teach and thats it. I didn’t fault him because it was his choice but i realized then that being a good mathematician dosent make you a good math teacher. B. Mclogan is a great math teacher.

[ibrahimjaved]

watching all of this guys videos a day before a test

[gelccc]

Omg allow me to shake your hand master, I needed this for one of the questions in my Cal quiz

[danielmaster]

Changing it from xy-y to y(x-1)? I never would have thought of that!

[Awre]

You are such a great teacher! Your students are so lucky

[tenishafields]

You just helped my Daughter who is an online student (Senior Year)!! We love you & thank *GOD* for you!!

[bungo]

No one was showing complicated examples of inverse rational functions thank you!

[elliotmyers]

Thank you sir. I was hung up on the part where you factored and it made perfect sense watching your video. Keep em coming, cheers!
