Today's class continues with inequalities. Like yesterday try to display the domains in x and y.

Inequalities in China and India

Welcome to the presentation on solving inequalities or I guess you could call them algebraic inequalities.

Welcome to the presentation on quadratic inequalities.

When you are working with inequalities in algebra

Inequalities you can treat them just the way

So it actually satisfies both of these inequalities.

Before we get to quadratic inequalities, let's just start graphing some functions and interpret them and then we'll slowly move to the inequalities.

And we have a system of inequalities right over here.

And then we still have our inequalities is going to be

So it's like 3rd class, 2nd class, 1st class.

Now, you might also see solution sets to inequalities written in interval notation.

In the inequalities, there's a whole set of x's that will satisfy this inequality.

I now want to solve some inequalities that also have absolute values in them.

India and China also have extraordinarily high inequalities, some of the worst in the world.

One billion that's more than ever before because of gross inequalities in distribution, not tonnage.
