what do i put the viewing window as on my calculator if i have an equation of
2x^2+40000/x
is x=0 an allowed value in the domain? So have to make allowances for x near zero. Check the problem: is x cited to have a particular domain? If not, then plot this in two parts
x large negative to near zero say x=-.1
second graph..
x near zero say x=.1 to large x.
Cheryl: My wife tells me that some calcs can handle the number/x when x approaches zero, but I havent ever seen one.
