jim_thompson5910 · Answer

how far does this function stretch to the left?

jim_thompson5910 · Answer

where does it stop on the left side?

anonymous · Answer

-6 and 6?

jim_thompson5910 · Answer

yep, the domain is from -6 to 6 (including the endpoints)

anonymous · Answer

So, A or B?

anonymous · Answer

How do I find that out?

jim_thompson5910 · Answer

hmm your answer choices are all messed up to be honest

jim_thompson5910 · Answer

for instance, look at  -2 > y > 2

how can you have a number that is both less than -2 AND greater than 2?

anonymous · Answer

I don't know

anonymous · Answer

What would be your best guess?

jim_thompson5910 · Answer

if you flip all the inequality signs, then it fixes the issue

but this issue is so glaringly bad that I'm not sure why it didn't get noticed by the teacher

jim_thompson5910 · Answer

the domain *should* be this:

{x |  -6 <= x <= 6}

anonymous · Answer

The teacher made the whole thing I think..

jim_thompson5910 · Answer

notice the direction of the inequality sign

anonymous · Answer

I will have to bring the topic up to the teacher
