Which ones can you rule out.
Do you think you know the answer etc
Other answerers:
Please allow loona to interact with me. Please do not answer over me.
+72 I think its either the first left one or the first right one because of the closed circle on -3, but I'm not sure about the other line
+118687 Yes good it is definitely one of the top ones.
The right side is the same for both so you only need to consider the left side.
g(x)=x
that is like y=x
So you can look at any points.
If x is 0 then y would have to be 0 So (0,0) would have to be on the graph.
So which is the correct graph?
+118687 Yes, that is the only one it could be.
With these multiple choice questions it is often easier to get the answer by elimination rather than by necessarily knowing which one is correct.
If 3 are wrong then the last one must be correct. ;)
+118687 You are very welcome. And welcome to Web2.0 calc forum 
I am always very pleased when askers interact with me. (And when they say thank you)
This would be true for all answerers here.
It leaves a very good impression and means that people are much quicker to give you quality help.
The other things that are appreciated is giving answerers point recognition by pressing the hearts icon.
I am saying this more for other answerers than for me.
For me, I'd like you to discuss your question a little when you first post.
That way answerers know that you have already made some effort and it may also help them hone in on which bit you are having trouble with. So you are more likely to get an appropriate answer straight away.
