Composite Function Explained - The Basics You NEED To Know!

In today's video, we're going over composite functions - what they are, how they're written, and how to solve them!

In short, a composition of functions is created when one function is used as the input for another. Sometimes, you'll be given an actual input value, which would first be solved in the interior function. Then, that output becomes the input for the outside function.

For example, f(g(2)), which reads "f of g of 2," would mean to first plug 2 into the "g" function. Then, whatever that result is, you'll plug that new number into the "f" function.

I can solve composite functions after watching this video no problem!

This is so helpful life savior, my understanding expanded! My teacher has been absent for a week and gave us this booklet with no other information on how to do it 😭😭

[chelseaf]

So the output becomes the input for the outside portion

Composite function is hard but this makes it seem easy

[graytheghost]

After watching multiple videos on this, this video is the only one that made any sense. Thank you so much 🙏

[lynnf]

So whatever the result of the g function is you plug it into the f function

[kelseykane]

So if your given an actual input value you have to solve it in the interior function

I started to attend my community college after been out of school for 36 years. Math has never been my strong subject, I have been watching math videos for a few hours and none have made sense until I found your video. I'm still not fully sure of composition of functions, but I was able to follow you. thank you for your explanation. it made sense.THANK YOU

Thank you! Your video helped me a lot, I was super lost

F(x) and g (x) don’t seem as confusing now

[juliesmith]

So a composite function is created when one function is used as the input for another ok!

You make people understood it's concept better rather than questioning things because u make math looks more beautiful, it gave me a bigger picture about how should i do for things i learnt ❤

[MarkusFavour-yu]

U are my savior after hours of struggling with this this part of functions

[epicmaster]

This dude just explained really well ❤ thank you g ❤❤

[PorkTheChop]

Still confused, what do I do if I have this in the equation; g(x)=x+4/2

[officialmonesh]

That's why I suggest my junior's of class 11th to don't study Physics chemistry but if you have choosen maths Study maths in very deep no matter what 🙂

how did u summarize two days worth of information that i didnt understand until now in just 5 minutes..???

[Carrymejane]

U guys will get used to it once u land in programming world

Of course it's not. 😅 f*g(x) is in no way similar to f of g of x.
