The limit as x→-∞ of (x + the square root of (x^2 + 2x)). I have to solve it algebraically. I keep getting DNE but when I graph it, the answer looks like it should be -1. Can you please show detailed work on how to do this problem or a similar one. Here's what I've tried but obviously something is wrong: *sq stands for square root of---
x + sq(x^2 + 2x) * (x – sq(x^2 +2x))
--------------------------------------------
1* ((x – sq(x^2 +2x))

x^2 – (x^2+2x)
------------------
x – sq(x^2 +2x)

-2x / x
-----------
(x-sq(x^2 + 2x))/x

-2
-----
1-sq(1-(2x^-.5))

I took the limits of each part to get:

-2
----
1-sq(1-0)

-2
----
0

DNE

It might be easiest to write this out on paper first because I couldn't type alll the mathamatical symbles -Thanks

On a gardening website it says that my plant needs 2 inches of water a week. What does this mean volumetrically?

Two inches deep gives a lot of variance, depending on how wide a container is.
