at least be specific

#

royal imp at least be specific

like graphs idk there is lowkey a few i dont understand

royal imp Dec 12, 2023, 11:19 PM

#

hybrid parrot like graphs idk there is lowkey a few i dont understand

any tasks or something maybe

hybrid parrot Dec 12, 2023, 11:19 PM

#

royal imp any tasks or something maybe

#

piecewise thing

royal imp Dec 12, 2023, 11:20 PM

#

hybrid parrot

nice next time just post this instead 😎

hybrid parrot Dec 12, 2023, 11:20 PM

#

oh aight my fault

royal imp Dec 12, 2023, 11:20 PM

#

did you try to draw it?

hybrid parrot Dec 12, 2023, 11:21 PM

#

i just dont know how to get the points

royal imp Dec 12, 2023, 11:21 PM

#

Well you should know how a parabola and straight line looks like for such tasks

#

Or do you mean which function where

hybrid parrot Dec 12, 2023, 11:22 PM

#

royal imp Well you should know how a parabola and straight line looks like for such tasks

i get that i think

#

i just dont get the points thing tbh or any of it the piecewise thing dont make any sense

royal imp Dec 12, 2023, 11:23 PM

#

hybrid parrot i just dont get the points thing tbh or any of it the piecewise thing dont make ...

ok

#

draw a coordinate system

#

and mark x = 1

#

the piecewise thing just combines multiple functions in one

hybrid parrot Dec 12, 2023, 11:25 PM

#

okay

#

after that what do i do

royal imp Dec 12, 2023, 11:27 PM

#

hybrid parrot after that what do i do

what function value is defined at x=1?

hybrid parrot Dec 12, 2023, 11:27 PM

#

royal imp what function value is defined at x=1?

2

royal imp Dec 12, 2023, 11:28 PM

#

hybrid parrot 2

so at x = 1 and y = 2 you draw a point

hybrid parrot Dec 12, 2023, 11:28 PM

#

okay

royal imp Dec 12, 2023, 11:28 PM

#

now if x < 1 meaning if x is less than 1 what function do we have

hybrid parrot Dec 12, 2023, 11:28 PM

#

x^2 + 1

royal imp Dec 12, 2023, 11:29 PM

#

so basically

#

you draw x^2 + 1

#

which goes from - infinity up until 1

#

then you stop

hybrid parrot Dec 12, 2023, 11:30 PM

#

how would i graph that

royal imp Dec 12, 2023, 11:30 PM

#

do you know x^2 ?

#

the normal parabola

hybrid parrot Dec 12, 2023, 11:30 PM

#

not really tbh

royal imp Dec 12, 2023, 11:30 PM

#

ok thats not good

hybrid parrot Dec 12, 2023, 11:31 PM

#

yeah i dont really got a teacher so i kinda self taught but i only have to get three right in a row then i move to the next topic so i am lowkey confused

royal imp Dec 12, 2023, 11:32 PM

#

hybrid parrot Dec 12, 2023, 11:32 PM

#

#

its online school btw

royal imp Dec 12, 2023, 11:32 PM

#

the thing looks like thi

#

the parabola is already given

#

you only need to place it to the rtight spot

royal imp Dec 12, 2023, 11:34 PM

#

royal imp

if this is x² then x² + 1 starts where

hybrid parrot Dec 12, 2023, 11:34 PM

#

aight y=1 right

royal imp Dec 12, 2023, 11:34 PM

#

hybrid parrot aight y=1 right

yes

#

and the parabola is drawn up until 1 then its cut basically

hybrid parrot Dec 12, 2023, 11:35 PM

#

so aight what point do i cut it

royal imp Dec 12, 2023, 11:35 PM

#

hybrid parrot so aight what point do i cut it

well for what x is the parabola defined

hybrid parrot Dec 12, 2023, 11:38 PM

#

i give up thanks for your help tho

royal imp Dec 12, 2023, 11:39 PM

@hybrid lake

#

nvm he left

#

🥲

Bro just asked and quit. Didn't even attempt 😭
