Re: Find Domain & Range

It seems you did it.
But on my side, I just see the file name of a hidden image which is 'IbFoc46.jpeg'.

Here is the image:

I don't know why it won't display as the syntax looks correct to me.

It works here too. Perhaps your image was uploaded in a different way.

Re: Find Domain & Range

Well yes. I examined the text behind the post; extracted the https; went to the image; took a screenshot; and then posted it again to my laptop account on Imgur. They haven't developed the android app to the same extent and it seems a bit random as to whether it works.

I'd rather not have to go through that routine every time.

Re: Find Domain & Range

Just a note.
Here, it is clear that:
Domain is for x (supposed being an independent variable) and Range is for y (supposed being a dependent variable, function of x).

This is a weird site.

Domain = (-3, 1]

Range = [-4, 2)

You say?

I give up trying to upload photos. This is nonsense.
Why me? Why always me?

Re: Find Domain & Range

domain good. range not.  The top y value is 0 not 2 .... that's an x coordinate

I was rushing by after getting home from my overnight job.

Range = [-4, 0)

Re: Find Domain & Range

Why did original link not work?
Maybe because Imgur doesnt like hotlinking that avoids ads?
but if you right-click (on computer) and pick 'open image in new tab' you get different url
Put that url inside image tags and you get:

domain: They show which bits of x-axis count
range: They show which bits of y-axis count

range: Graph does not go up to y=2
It stops at y=0 (x-axis)

Thanks. Moving forward, I will use this site to post questions that are not explained in the textbooks and problems that I simply get stuck on. There's no need to clog the forum with problems that I obviously know how to solve. Do you agree?

Re: Find Domain & Range

Yes. I get a bit overwhelmed when there's a line of fresh posts; some of which are asking for a hint and some are just making a post solution comment.

But keep asking when you need it and we'll keep answering

Bob

ps. No need to reply further for this reason.

Ok. Copy. Will do.

P. S. I need help in terms of making a decision about a job. Do you have an email address? I have no one to help me make the right choice.
