quick question

[bailey07]

I3xI if -3<=x<0
x^3 if x>0

the points i came up with are (1,1) (-3,9) & (0,0)


i know that (1,1) & (-3,9) have closed circles but i'm not really sure about (0,0)..i think it may have an open circle..if someone could please answer this i would definately appreciate it..thanks! :]

Sadly, your question was so "quick", that you didn't actually provide the question. Care to try again?

sorry i meant to ask if (0,0) has an open or closed circle

Unless you just forgot to put "=" on one of those definitions, definitely an open circle.
