ok, that works, thanks for the help. i'll post if i run into anymore problems

ok so the next problem is the limit as x approaches infinity for (2+x^1/2)/(2-x^1/2). the answer i got was -1.

ok, i think i get it now. so the answer for number 3 would be 9/2 as it approaches infinity and the same as it approaches negative infinity?

ok, i think i get those two better. so for 3, id start by trying to factor, which i don't see anything that factors off the top of my head...

oh duh, ok, so what do i need to do to figure out the answer, plug in zero?

they're getting closer to infinity...

1 over infinity?

i don't exactly get what you mean. what number would i need to put in? answers for number 1 are both 1/2 and the answers for number 2 are both 2/5. the answer for 3 isn't in the book

Homework Statement Find the limit of each function (a) as x approaches infinity and (b) as x approaches negative infinity Homework Equations 1. g(x)=1/(2+(1/x)) 2. f(x)=(2x+3)/(5x+7) 3. h(x)=(9x^4+x)/(2x^4+5x^2-x+6) The Attempt at a Solution I don't know where to start.

a=-1 and b=1, i don't have an algebra book but i got it somehow. do i need a new thread for each new problem i have?

haha sorry it is in my calculus book. you i think i do. but how would you get a and b then?

Homework Statement Find the constants a and b such that the function is continuous on the entire real line. Homework Equations f(x)={2, x< or = -1 {ax + b, -1<x<3 {-2, x> or = 3 The Attempt at a Solution I don't know where to start. If anyone is willing to help...
