Question

Accepted Answer

use the number line to demonstrate the set negative 3 to 4 in the intersection, negative 2 to 7. Let's go ahead and figure this out. You notice here we have a number line negative 3 to 4. Let's go ahead and draw it out. I will go 7-94, six and seven. Now in red I will put our set negative 3-4. So we started negative three. We want a closed circle because we have a square bracket because it's a four open circle because we have a round bracket. Let's go ahead and show our Atlanta. Now let's try negative to the seven. So -2. We have an open circle And the seven. We also have an open circle so we'll go ahead and draw another line all the way up there. Now the intersection symbol or just downwards you that means we only want the part with a sets overlap. If you look here We started negative two and go to four right here. Those are the parts where it overlaps so interval and some negative 2-4. Now we want to look at our parentheses, since we have an open circle negative two, we will use a round brackets or parentheses at four. We have an open circle. So it also use a round bracket that means safer line As a line with two open circles from -2 - four. If you look at our graphs, the answer to this problem is actually answer a where We have an open circle native to an open circle at four. Okay, I hope to help you solve this problem. Thank you for watching Goodbye.
