Homework Statement

the problem, where you want to find the one sided limit is
Lim (2x^2+x+1)/(x+2)
X=>2-

Homework Equations

The Attempt at a Solution

Well i did attempt the problem. All i can think to put as the answer is finite.


I'm basically teaching myself calculus which as you can imagine is all sorts of fun. I know how to find limits, and how to do stuff like that but the one sided limits throw me off. Please help.

Hi BBrttnybrat,

The function you gave is continuous at x=2, so the limit is just the value of the function at that point. Did you mean the limit as x -> -2 from the right, i.e. x -> (-2)- ?
