Could you give me some hints on how to answer these two questions?

1: Describe the graphs of the functions f(x) = 2x – 1 and g(x) = –2x – 1.

2: Compare and contrast the domain and range of f(x) and g(x).

Have you graphed them and taken a look?

strawberry17 · Answer

yes..

baldymcgee6 · Answer

okay, well.. If you notice, the slopes are opposite

strawberry17 · Answer

I have a hard time with asymptotes. I do not understand how to identify them in graphs.

baldymcgee6 · Answer

That's because there are no asymptotes in the graph of these two functions.

strawberry17 · Answer

My teacher asked me, "What is the asymptote that the new graph gets closer to" when I asked her for some help..

strawberry17 · Answer

I do notice that the slopes are opposite though..

baldymcgee6 · Answer

tell your teacher there are no asymptotes in these to functions; assuming these are the two functions you are talking about and there are no typos

strawberry17 · Answer

okay

baldymcgee6 · Answer

slopes are opposite, and they both have the same y intercept, this point is called an invariant point. (where both function intercept.

baldymcgee6 · Answer

domain and range is the same for both, $$domain = XER$$ $$Range = YER$$

strawberry17 · Answer

the same y intercept, is that -1, and on the graph are both graphs supposed to cross it?

baldymcgee6 · Answer

Yes, same y int at (0,-1)
Both functions intercept it at that pt.

strawberry17 · Answer

okay. Thanks for your help :)
