Ah, the haunting nightmares of inverse functions – the nemesis of many a math student. They lurk in the shadows of our minds, threatening to unravel our understanding of mathematics. But fear not, for in the midst of your despair, there emerges a hero – none other than the legendary figure known as 1st Class Maths.

With a name like that, you can almost envision a caped crusader swooping in to rescue you from the clutches of mathematical doom. 1st Class Maths, armed with unparalleled knowledge and expertise, becomes your beacon of hope in the dark abyss of inverse functions.

As you grapple with the complexities of inverses, struggling to comprehend their elusive nature, 1st Class Maths appears as a guiding light. With patience and clarity, he navigates you through the treacherous terrain of mathematical inversion, unraveling its mysteries one step at a time.

Through his teachings, the once formidable foe of inverse functions begins to lose its grip on your consciousness. No longer do you dread the mere mention of inverses; instead, you approach them with newfound confidence, armed with the tools bestowed upon you by 1st Class Maths.

And so, thanks to the guidance of this mathematical maestro, you emerge victorious from the battleground of inverse functions, no longer haunted by nightmares of their complexities. In their place stands a sense of accomplishment and mastery, a testament to the transformative power of a skilled educator.

Indeed, when faced with mathematical adversity, it is not uncommon to seek solace in the wisdom of those who possess the knowledge to illuminate the path forward.

Thank you so much! I've been having to teach myself gcse higher maths before mocks - we're doing a full paper, and I need an 8 to do further at sixth form! - as my class hasn't covered all the content yet. This channel has been invaluable.

I have my maths olevels in a few hours. Thank you for this!!

Once again here i am binging your videos the day before my paper 3 gcse exam this time! You helped me understand inverse functions which I always struggled with, especially with all the simple steps ty. Also i have a question, for the 2nd example if my answer was 5x-1 instead of 5(x-1), would it still be correct?

Thank you for this video. Helped a lot!

Hey this is super helpful, also what is the difference of doing (the cube root of [(x squared - 58) divided by 2]) and ([the cube root of (x squared - 58)] divided by 2)? sorry when written its super confusing lol

[constancedolamo]

Thanks
Only few minutes into the video Nd I was able to reverse an inverse and also turn a function into an inverse❤😊

Why we are replacing x with y and y with x in step 2

Thank you so muchhhh, my GCSE pp2 is tomorrow and I didn’t understand this topic, it’s so much easier now you’ve explained it! 🫶

[danmike]

Again great explanation of the topic .

[callblackoutswiss]

It's just clicked, I can now visualise It

[afkgamer]

Sir something I dont understand.
f(x) = x/5 + 1
f-1(x) = 5(x-1) <-- Thats your answer

But, can you explained this:
f(x) = 3x - 4 / 2
f-1(x) = 2x + 4 / 3 <---- The answer

Why it is not:
3x = 2(y+4)
f-1(x) = 2x + 8 / 3 What im doing wrong???

Plz can you start a level and as level math
