yes,I know,now I want to know how do you call it in your country,we call it "nike curve" in China,I want to know how do you teach your students in maths teaching?did you use the sketchpad to graph it??
I graphed it use Graphmatica, give that a search in google and its free.
You don't need to call it anything Sophia, just tell the students f(x)=x+1/x. That's all. And just incase you wanted some helpful info on actually graphing it, its an odd function so theres antisymmetry. and www.calc101.com has a graphing program on it, that might help as well.
