Solving the Composition of Two Functions

Learn how to compose two linear functions. To compose two functions means to express one of the functions as a function of the other function. This is done by replacing the input variable of one of the functions with the value of the second function. We will then simplify the composition and determine the domain.

[@brianmclogan]

Hey thanks for letting me know! I did a couple of other videos on composition of two functions this year, hopefully I went slower on. Going to fast is something I am trying to work on. Thanks for letting me know!

[@josephrahme6937]

Just came across this channel and just wow! Made everything that I am learning from my current algebra professor understandable. Thanks for keeping the explanations simplistic!👍

Hello 👋 But why did you choose -3 ??

[@TWENTYSEVENSTORIES]

Why not?

[@4th19th2]

Just as an example.

[@daliyah1997]

I am a little confused about what happened after the substitution of f and g of x.

[@shenkorinabogale2205]

U are the reason i will score good math score on my mid term exam

[@brianmclogan]

Yes!!

[@devinjones441]

I love you so much bro

[@craigwalter2051]

So what would be g(f(x))???

[@littlekoo5691]

Suddenly Im not confused anymore how to do this

[@lincejoshua7071]

Hey Brian, I am still having a hard time learning composition of functions on Khan academy even after watching some videos as well. I don't what the problem. It might just be me or it's the way that I am trying to plug in the numbers.

[@brianmclogan]

Usually it’s the notation that takes a while to get used to but keep practicing and trying different examples. You got this!!

[@bellamuetzel1975]

i love u thank u

[@pro_pvp0992]

Why is it negative 3 im so confused

[@deshaunwilliams9189]

@DeadEndPage I guess I am glad you understand me then!

[@michellewu3132]

[@laptopuse2689]

YOU ARE GOD SIR

[@swan_kytiger]

[@brianmclogan]

So happy to help!!

[@brooksblair5887]

this is still crimminally confusing i understand how to do functions just fine, so why cant i understand this if its just a function of a function?

[@Yello693]

I still don't understand

[@brianmclogan]

do you have a question for me then?

[@ericacheyenne1137]
