I'm new to GH and am just trying to get used to how the components work. As a start I've been using the Range, Function, Point and Interpolate Curve objects along with some sliders to draw a simple polynomial (ax^2+bx+c). I notice that I can't get the domain of the function to cross through zero. It's either zero+ (0,1,2,3,...)or zero- (0,-1,-2,-3,...) but not -zero+ (...-3,-2,-1,0,1,2,3,...). Consequently the result does weird things near zero. Is it related to the nature of the curve being used to draw the polynomial or am I misunderstanding something about setting this up? Thanks for the help.
