Using long division, we can calculate that f(x)=(2x^(3)-16x^(2)+7x-38)/(2x^(2)+5)=Q(x)+(R(x))/(2x^(2)+5). Determine the quotient and remainder. Quotient Q(x)= Remainder R(x)= From this, we can conclude that y=f(x) has an oblique (or slant) asymptote given by the line with equation y=Q(x) y=R(x) because lim_(x->+-infty )(R(x))/(2x^(2)+5)= Using long division, we can calculate that R(x) 22+5 Determine the quotient and remainder. Quotient Q(x) = 9. Remainder R() = From this, we can conclude that y = f(x) has an oblique (or slant) asymptote given by the line with equation O y=Q(x) O y=R(x) R(x) because lim 2x2+5

PHP supports only single inheritance; it means that a class can be extended from only one single class using the keyword 'extended'. 12) What is the meaning of a final class and a final method? 'final' is introduced in PHP5. Final class means that this class cannot be extended and a final method cannot be overridden. 1. Create a database called UNIVERSITY. (user name = root, password = "") 2. Create a table called STUDENT inside the UNIVERSITY database with the following fields: [stNo, name, age, average], stNo is the primary key 3.
