Find the critical points, then find and classify all the extreme values in:

f(x) = 2x^2 +5x -1, for x in the interval [-2,0]

I have about 5 problems similar to this, but if you can show me how to do all the steps in this one, I think I can do the rest. Thanks :)

I need the answer to this ASAP! Please help if u can...

I thought it might be because of the plates underneath of them converging or whatever the words is. But then I looked in my notes and all they have under The Himalayas is erosion-the process whereby materials on the surface of the Eart are broken down and transported. But why would that be the reason? Or is it?

Please help!!

Why is it that people today are unwilling to deal with any kind of pain? Always reaching for drugs for the littlest thing. Don't get me wrong, I can certainly understand taking drugs if you're in moderate to severe pain, that's understandable, but to pop a vicodin for period cramps? down a handful of advil for a slight headache? Have a tiny cavity filled needing 4 shots of novocaine? Drugging yourself almost unconscious to have a baby? Being put under for a colonoscopy?
Doesn't anyone "tough it out anymore?" Have we turned into a society of wimps and drug addicts?
Please don't respond with "why have any pain when you can pop a pill and not have the pain."
I'm asking this question because 20 years ago people were alot tougher than they are today and I'm curious as to why that has changed so drastically. Nice, Intelligent replies only please!!
