It's for a friend so I actually don't have the work rn. I was just trying to help em out.

[indigo viper]

i think the reason its wrong is they didnt round

[unique leaf]

so how about this then

[indigo viper]

limits are only defined when approaching from every possible direction gives the same answer

and as you can see by the table, that is not the case here

[indigo viper]

actually no they also did the 4 - xx wrong, apparently

this is the function

[indigo viper]

but yeah this is something to watch out for

[unique leaf]

I see

So what would they need to put for question 1 and 2?

just to make sure

@indigo viper

[indigo viper]

well i shouldnt give the answer but they should put 4 - x^2 in their calculator, then cut off everything after the 2nd decimal place, and should do the same but for x^2 + 2x

and the limit is actually defined here
