Write each set in roster form and in set-builder notation. $R$ is the set of even natural numbers that are less than 2

All right, so we've been given the set C equals and such. That end is an even number between negative 15 and negative five. So this isn't step builder notation, and we need to convert this to roster form. So with thruster form, we just kind of need to figure out what these numbers are. So the nice thing about step builder notation is that they've given us hints about how to figure out what those numbers are. They've told us that and has to be even numbers. There has to be between negative 15 and negative five. So we're looking for all of the even numbers between negative 15 and negative five. So let's just look at all of the numbers. In between them, there's negative. 14 Negative, 13 negative, 12 Negative. Turn our sorry negative 11 negative. 11. Make it 10 89 negative. Eight negative and negative six. And now we just have to pick out the even numbers. So enough, negative 14 is even negative. 12 is even negative. China's urine negative eight is even, and negative six is even so these air gonna be our numbers and we just have to hit list about. So that is how you convert a set from Sepulcher notation to roster for

So we want to make upset A and B such that the union has three elements and there is no intersection. The intersection of the empty set. So what if we went Hey the, um one and to and said d just be three. Then a union be would be equal to 12 and three. So it has three elements in the intersection. There is no intersection between them. It's the empty set. Well, actually, this would be our answer.

In discussion you use go strips notation you die the said off letters in the world Any Divina the start by adding each sector well, that's a without the beating letters a coma Romare z Roma e one b

Our guys that were asked If I why intersect with union? See? So let's start with ex Union and see. So actually union between that's equal to we have 123468 and nine. And now we're asked to intersect that with why. So we see we have a two in common 13 for full and six, so this is equal to 23 four and six.
