what do you not understand exactly?
elfin patio
Q2 : I don't see where you are finding your -5 here.
it isn't -5, do you see why?
severe prairie
I was pointing that mistake out to them I'm not OP.

I was pointing that mistake out to them I'm not OP.
oh my bad i thought you are the op😅
severe prairie
It's fine hhh
vital siren
Other than it everything is correct?
severe prairie
At first and quick glance yes.
severe prairie
Yeah AI sucks unfortunately.
It's a shame you weren't given answers for your exercises, I can understand how annoying it is to not know if you're doing stuff right.
vital siren
-7 question 2 i had it
Yes its a shame still in school but idk whats correct or not tbh i wanted someone to review it before i attend my test in a few hours
Is -7 correct
Hello @severe prairie
vital siren
NO?
severe prairie
First off the lines don't both approach the same value
Second off neither of them approaches the value -7
vital siren
6
severe prairie
Start with approaching from the left
If you follow the line from the left what's the value it's approaching?
vital siren
-10**
severe prairie
No
The line almost reaches the point (-2, -9)
So the left handed limit is -9
What about the right handed limit?
vital siren
What the heck this is so difficult abd a few hours to understand
severe prairie
You had all the others it's not really a different idea
You just follow the function from the left approaching x=-2 and see what value it seems to take. Then do the same from the right
severe prairie
What the hell
Also this is wrong. Stop using AI it's making you lose time over nothing and it's giving you bogus reasons that will only make you more confused.
Like "oscillation = DNE" is bullshit and has nothing to do with the question at hand.
vital siren
But i just wanted to ensure everything is correct to my understanding
severe prairie
I get it but there's also tons and I mean TONS of exercises like that available on Google/YouTube and those will probably have answers as well, and those won't confuse you and will explain the reasoning better and more accurately that ChatGPT.
vital siren
What about the right handed limit?
Is it -6
vital siren
I get it but there's also tons and I mean TONS of exercises like that available ...
Thanks i will check on q12 and q9 later on idk whats happening
severe prairie
Is it -6
No. (-2,-6) is the lone point on the image but if you follow the line on the right it doesn't approach that point ...
Q9 is right. I think it's just analyzing the image wrong and thinks you are asked to compute the limit at x=-8, which doesn't exist, rather than the limit at x=8. (note that this is an added source of possible hallucination from AI)
And Q12 is also right. The fact that there's weird oscillating bits along the way doesn't change the fact that you're given the horizontal asymptotes...
vital siren
No. (-2,-6) is the lone point on the image but if you follow the line on the rig...
So -5?
severe prairie
The red line on the right.
If you follow it along to x=-2, from right to left
What point does it approach?
vital siren
-2,-5
I think
Not too sure
Verifying the answer is whats diffcult whole time thought i was fully correct
severe prairie
Left arrow is what you should imagine when taking the left sided limit
Right arrow is what you should imagine when taking the right sided limit
The arrow on the left points to (-2,-9).
The arrow on the right point to ...
Do you see how it can't be (-2,-5)? That would be a point way above that where the arrow is pointing.
severe prairie
Yes
vital siren
HOLY RELIEF
thank you so much i will do this on my own now but any other things i got wrong?
severe prairie
Of course if the function (i.e. red line) is wiggly then you'd have a wiggly arrow I guess, but the ideal is you follow the function until that point and see where it points.
severe prairie
thank you so much i will do this on my own now but any other things i got wrong?
No the rest was good
vital siren
Thank you so much
Btw where do you learn from?
I will close the thread now thank you @severe prairie
severe prairie
I think for limits and stuff like that Khan Academy is good since it has interactive applets that let you try stuff out
vital siren
Thank you how do i close the forum up if everything is correct now
