goodyhi11 Posted March 29, 2005 Share Posted March 29, 2005 my problems is i got stuck while i was trying to find the domains of a function, 1) f(x)=(x^3)-(3x^2)+(2x)+5 2) g(x)=(x^2)+5/(x+2) can anyone determine the domain of the two functions? Thanks a lot! Link to comment Share on other sites More sharing options...

Dave Posted March 29, 2005 Share Posted March 29, 2005 try rephrasing your question. this isn't "homework answers", it is "homework help". Try rephrasing your post to include some manners and politeness. As for the actual problem; the first should be fairly obvious. The second is trickier; you can see that x = -2 yields an undefined value for g(x). This should give you a clue as to how to find the domain Link to comment Share on other sites More sharing options...
