1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

so when evaluating where f(x) is not defined and f(x) is rational, we need to set the denominator equal to zero and solve for x

it is prohibited to send the answer

we need them to work through it

although it isn't specifically the answer, you can still get the answer from what u posted

so for example: Find the domain of $f(x)$ such that $f(x)=\frac{1}{2x+1} \$
$2x+1=0 \to 2x=-1 \to x=\frac{-1}{2}$ so $\frac{-1}{2}$ would be from the domain since you cannot divide by zero.
so the domain would be $(- \infty, \frac{-1}{2}) \union (\frac{-1}{2}, +\infty)$

$2x+1=0 \to 2x=-1 \to x=\frac{-1}{2}$ so $\frac{-1}{2}$ would be exluded from the domain since you cannot divide by zero.

and if you are unfamiliar with interval notation, here is a good video showcasing it https://www.youtube.com/watch?v=djT6-YamHaA it also shows how to find the vertical asymptotes

also since this is a square root, remember that the parent function, $\sqrt{x}$ has the domain $D: x\geq 0$

and use that when finding the domain

so like:
$\frac{1}{\sqrt{2x+1}}$ would have the domain$ D: x>\frac{-1}{2}$ since $\frac{-1}{2}$ would yield zero which is undefined

remove the answer

you aren't helping anyone with posting answers

this too

[rain frigate]

i think this is help forum

[quaint tulip]

yes

you would be correct

but this is not give the answer out forum

[rain frigate]

if i voilated rule please link rule

[quaint tulip]

again, don't just give out the answer

you are helping no one by posting the answer instead of guiding people

[rain frigate]

ok understand rule

[quaint tulip]

so delete it
