Question 14 5 pts lim Find lim x-too f (x) and x- J (x). If the limiting value is infinite, indicate whether it is too or -co. f(x) = -3-x+7x2-3x3 O lim lim x -too J ( x ) = too; f (x ) - -co O lim lim x-too J ( x ) = -3 ;, f (x) - 3 O lim lim x-too J ( X ) = - Of(x) = too O lim lim x-+too J (x) = -3, f(x) =-3
