Question

Quick question. What's the domain for this?

Answer 1

for what?

Answer 2

I'm not sure if it's \(-6<x<3\) or \(-6\le x \le 3\), but I'm PRETTY sure it's the first one.

Answer 3

I know I didn't include the points, but that's what they are, lol

Answer 4

@imqwerty

Answer 5

the open circles means the relation doesn't exist there

Answer 6

your relation is not defined anywhere else for x=-6 or x=3
so you definitely will not include x=-6 or x=3

Answer 7

So the first inequality was correct?

Answer 8

yes you don't want to include x=-6 or x=3
and your second inequality does that
that is what the little horizontal lines under the inequalities mean
less than or equal to

Answer 9

yea the 1st inequality is correct cause the values -6 and 3 are omitted in the graph :)

Answer 10

Yes, I know that part @freckles. haha

Answer 11

Thanks!

Answer 12

oh then I guess I wasn't sure why you were asking why not to include the equality part

Answer 13

Idek why I was uncertain. I think it's because it was a circle and it was on both sides, but I don't know XD thanks thought :)

Answer 14

if it was this then you say:
\[-6 < x \le 3 \]

Answer 15

or if it was this then you would say:
\[-6 \le x \le 3 \]
