Since no one has mentioned this yet, when you add/subtract graphs you can draw the two graphs you need to add/subtract and from there you manipulate the y values. In addition, you add the y values together at that x point, though I recommend only adding the "nice" y values. In subtraction, you...

That's a much simpler solution! Awesome! :D

It's too complex!

That sounds reasonable enough but I still find that a very iffy question. > ^ < Thanks for that Aesytic! At least I can sleep easy lol.

Derp wrong question. Soz bro.

Lolyeah pretty much.

My 2u assessment is on tomorrow.. so hopefully there won't be a question like that!

Could you email your teacher and enquire about that question? Answers even school test paper answers can be wrong.. or.. maybe we're missing something. D: I kinda wanna know how that works. :L

Does that mean the graph can be differentiated outside that given domain? Which is probably the question you are asking.. and to be honest, I think that is the only way you can do it because you're absolutely correct, end points cannot be differentiated. :)

Hi, not sure if you have answered the questions by now.. but here is one way on how you can do it. Sorry I don't actually know how to draw tables on this.. s: -noob- 1) If a plant with green pods self fertilised and managed to produce offspring with yellow pods, this indicates it must have...

Re: HELP!Examples of physical conditions/chemical conditions and competition for reso Hi, I'm not quite sure these are examples but as long as you understand the concept, I'm sure you can think of more examples. Physical change So an example of this would be the emergence/adaption of...

Hi do you have the answer? I think I have it but I'm not sure... > ^ <
