hello brother I’m doing graphing questions on edge unity and I’m getting them wrong it’s mad stressful
okok
like using first derivative and second derivative of a function?
can you show me
Sorry I took these on my laptop I hope they’re fine
Even on things like brainly it gives me the wrong answer it’s super baffling
oh
so the derivative is the slope of the graph
the slope is 0 when x<0
because it's flat
and the slope is -1 when x>0
because it's linearly decreasing 1 for every change of 1 in x
man I seriously despise graphing
Dude I tried to use ai and brainly and it’s still getting crap wrong frl you’re a real one I appreciate you
what if you build a line that touches that point once
and what the slope of the line be
so the derivative is 0 for x<0, and -1 for x>0
so the first image is the derivative
It’s 0 when x is over 0?
no
-1
because the slope is -1
it looks like
\
which looks like the graph y=-x
Random question but what math level are you you seem mad competent
i finished calculus
Idk how I passed Precalc bjt I did that and then ab jus crushed me man
Ab is jus 1
i didn't do IB or AP
Sorry are you able to stay for a few more graphs or only like one more
Why lmao
yeah sure
hes so chill
This means a lot to me gng I can’t graduate if I don’t do these online quizzes 😭😭😭
Yeah it’s a little stressful
I’ll send the next one over thank you so much
a non-differential point is where the derivative doesn't exist
Gotcha
which means that you can not define a slope at the point
So what would that mean for the appearance of the graph?
and vertical tangent is essential when values approach infinity near the point
so the slopes would be approaching infinity near the "non-differentialble point"
Dude omg I could not comprehend limits I had to use that l hopital shortcut but I forgot it long ago
all of them actually have a non-diffential point, but only one has is from a vertical tangent
no its from the appearance of the graph
So only one graph is approaching infinity from the non differential point?
yes the slope is approaching infinity/negative inifinity
near the non-differentialble point
It’s the second graph instead?
so it is approaching the slope \ near the point
the second graph is also approaching the slope \ near the point
it's the fourth graph
because the slope looks like " | "near the non differentiable point
which means the slope is approaching infinity
Man this shit is crazy lmfao
I seriously envy people who got a natural aptitude for math
on my course
Mostly imahes
What about x-1 particularly ?
yes
and infinity means vertical tangent too
others ones are "non-differentiable" but not infinity
This one seems to follow a similar pattern
About being non differentiator
Differentiable*
so at x=-1
no i mean for all of them we should see if the slope exists
no
wait nvm
yes
so
do you know the definition of limit
if that can be a value at a point, it is differentiable
Isn’t that when like it’s approaching smth mad close but it’s not quite touching it
Like instead of 1 it’s 99999999
yeah
so like
f'(x)= lim(h->0) ......
if that exists
it's differentiable
because differentiable means derivative exists
It doesn’t exist when there’s like conflicting values or smth right? I could be way off but I rmbr hearing smth like that
That sounds hard as heck
Really?
at x=-1
the slope from the left side is some number, while the right side is 0
at x=0, the slope is inifinity
Oh so it doesn’t match up?
at x=1, slope is 0 from the left side, while it is -1 from the right side
Therefore creating a non differentiable thing?
yes
Jeez bro you’re cracked
thank you
:D
and at x=2, the slope is -1 from the left side and 1 from the right side
so the slope exactly at x=2 doesn't exist
It keeps changing?
yes
How the hell do you keep all this in your brain beother
on the graph f
😭
the graph f when x>0, it's slope is increasing
The slope increases when x is over 0?
like from ㅡ to /
Or maybe the first one
I think I only have one more graphing one the rest are word problems and I don’t think you wanna sit thru sentences and crap
Are you down for one more graphing one?
Thank you so much bro.
youre welcome
i like helping people
i might apply as a private tutor as a job maybe
It’s good money on the side fs
They love throwing the worst questions at me lmaoo
Alright
so the derivative is always going to be positive
because derivative is like the change of y
I’m noticing that y at the end (7.5) is slightly bigger than x at the end (7) so would it be the first or second graph?
and we'll look at the "how much of" change of y we experience
Or is that just random speculation
no that's kinda random
Mm how would you go about it
Right
so the slope is tiny at the start, thus derivative is tiny at the start
yes
On the third one am I tripping or is x at 2 and y at 1
It seems proportional
Although guessing eveyr graph doesn’t exactly mean anything either
it's the change of the values that matter
it could be y=99999 when x=1 and the derivative could still be 0
because the change could be 0
on the graph the change is not that great between 0 and 2.4, greatest between 2.4 and 4.8, and the second greatest between 4.8 and 7
yeah
because the value of the derivative represents it's rate of change
so the derivative is small between 0 and 2.4, really big between 2.4 and 4.8, and kinda big between 4.8 and 7
which is graph 3!
Then which of the 4 graphs represents the rate of change the best? Cuz clearly going by the appearance won’t help me
Ohhh it was 3???
it should be graph 3
this is a bad question
my calc teacher would be angry lol
yeah
This is what I got last time I took it
graph 3 seems to have values that are more accurate
Ong what does solving real problems even mean 😭😭😭🙏
I’ll go with graph 3, thanks for your help bro
lol
@simple dawn omg dude I just barely passed it with an 80% you can’t proceed under 80% you are the GOAT bro
LETS GO
Bro go torture kids at kumon it’s your destiny 😭😭😭
I wish I could pay you or smth bro
@simple dawn do you have like an Amazon wishlist I got like 2 more tests later in the unit and i could get you like smth on your Amazon wishlist
you down to help clutch those last two when I make it there?
yeah im down
Lmaooo bro got a chill and easy life frl
I really jus be spending jt on food
I spend too much on random fast food lol
Anyways these threads eventually clsoe rigjt
Yeah could I just dm you later on gng
for sure
@languid cairn it's a bannable offence to ask for help on quizzes on tests, fyi. @simple dawn so is helping on them (if you know it's a test)
You can (and should) manually close with .close or .solve
Ah dang sorry brother I’m new
Won’t do it again 🫡
.close
