a lot of abs functions satisfy it...?

[fringe abyss]

?

[worthy finch]

Let f(x) = a|x| + b

I think this will work

[fringe abyss]

Alright

What do I do for a an b tho

[worthy finch]

Same as you did in (a)

[fringe abyss]

But there's a b

• b

[worthy finch]

For x = 0

F(x) = 2

And b = 2

For x = 1 , f(x) = 8
8 = a|1| + b
8 = a+2
a = 6

Finally f(x) = 6|x| +2

Well i m not 100% sure if this is correct or not

[fading garden]

f(x) = 6|x|+2 will do

Correcto

[kind widget]

Among functions of the form f(x) = a|x-k|, there should be a unique one satisfying the problem setting

[fringe abyss]

Where did you get 2 from..?

8=a+2

[robust summit]

the point 0,2

sub x and y into it

[fringe abyss]

Bro what

[fringe abyss]

Then where did 8 come from..

How did b = 2?

[worthy finch]

Bruh it's same as you did other 2 questions

[fringe abyss]

My brainnn

[fringe abyss]

What happened here??

[worthy finch]

, rotate

[fringe abyss]

How did you get b=2 when there no value for a

Did the a just dissapear?

[worthy finch]

0 ×a = 0

[fringe abyss]

Wouldn't I be 0a? 😭

Now I'm lost

[worthy finch]

What what?

[fringe abyss]

You can't multiply with a variable to make a number

Or can you

I'm lost

[worthy finch]

🥲

[fringe abyss]

Alr well I guess you can

[worthy finch]

Yea

[fringe abyss]

How did

F(x) turn into 8

[worthy finch]

It's given in question

F(1) = 8

[fringe abyss]

Oh do you pick another

Point

Not the same poont

[fringe abyss]

Doe I matter

[worthy finch]

Yea

I used both points

[fringe abyss]

Doe it matter

[worthy finch]

Wdym?

[fringe abyss]

Does it matter whether you pick the same point or not

Does it matter which point you choose

[worthy finch]

Generally we need two info to eliminate two variables

[fringe abyss]

Oh ok

[worthy finch]

Or parameters

[fringe abyss]

I got it now tho

I got the same answer you did

[worthy finch]

Congo

[fringe abyss]

Thank you for the help

[worthy finch]

Yep welcome
