Question

How would you graph this interval notation -13/2 13 years ago

Answer 1

I'd start by changing those improper fractions to mixed fractions

Answer 2

I mean is it going to go right or left? Is it going to have opened or closed circles?

Answer 3

Well, according to the inequality you posted, x are all the values between -13/2 and -7/2. There are no equal signs under the less than symbols, so those endpoints are not included in x.

Answer 4

so they would be opended circles?

Answer 5

Yes, correct, the endpoints would correspond with open circles on a graph.
