  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

the x not equal 1 and x = 1 confuses me

Do you know how to find a limit in general?

What

#

You mean what part of f(x) to use?

manic crane
#

cuz this is the answer but how they got 0

keen shadow
#

Okay

#

Did you understand the function?

manic crane
keen shadow
#

Okay

#

It is y = 1-x² mostly

#

Only that, for x =1, it is 2

#

Get it?

manic crane
#

oh yes ok

keen shadow
#

Ok then

When you find the limit of a function what do you look for?

manic crane
#

like this?

keen shadow
#

That is y = 1 - x

manic crane

#

Right.

#

To find lim x-> a f(x). We find values that f(x) approach as x approaches a

#

Does f(a) matter?

manic crane
#

No..?

keen shadow
#

No

#

So to find lim x->1, just don't worry about f(1), that is 2 in the question

#

Just find lim x->1 1-x²

manic crane
#

yea plug in 1 = 0

keen shadow
#

Yeah you get 0

manic crane
#

ok i was overthinking it

#

Thank you!
