What was done on this step

[feral shale]

Presumably f(x) = 2x+1

[rotund frigate]

Oh yea sorry I keep forgetting to show the original question

[frank field]

not me wondering what the actual heck was going on lmao

[rotund frigate]

haha mb

[frank field]

ok

got it

in order to reach the line u pointed u need to do f(3x+1)

do you know how to do f(3x+1) ??

[frank field]

dw

[rotund frigate]

wdym "do"

[frank field]

like, elaborate f(3x+1)

its like when you get f(2)

u just substitute the x

so

if you had f(2)

u would elaborate it as:

2(2) +1

right?

here is the same

[rotund frigate]

yeag

[frank field]

now, elaborate f(3x+1) and you will get your answers

[rotund frigate]

would it now then be:

3(2) + 1

[frank field]

no

look

f(x) = 2x+1

f(2) = 2(2) +1

you substitute the x with whatever it is in the parenthesis

[rotund frigate]

so you subsitute x with f(x)?

[frank field]

for example

if you had f(2x)

u substitue x as 2x

look:

f(2x) = 2 (2x) +1

u see that?

[rotund frigate]

yeah

[frank field]

well, now elaborate f(3x +1), same moves

[rotund frigate]

its a bit wierd though, would you not use a different variable cause your implying that 2x = x

[rotund frigate]

3(2x) + 1

[frank field]

the other way around

2(3x+1)+1

f(x) = 2x +1

[rotund frigate]

ooooooh

I get it

[fallow tangle]

x is just a placeholder in f(x) = 2x
so whatever you put in parenthesis you replace it with x

[frank field]

f(3x+1) = 2(3x+1) +1

[frank field]

yaayss

:>

[rotund frigate]

:DDDD

[fallow tangle]

f(⭐) = 2 ⭐

[frank field]

now, u shall continue your lines

[rotund frigate]

yessir

ty

[frank field]

clever way to explain it

[fallow tangle]

thank u

[frank field]

np !

[frank field]

remember, should you reach the answer you wanted, close the thread

[rotund frigate]

how

wait nvm
