Question

Describe what the graph of interval [-4,10] looks like.

Answer 1

A line graph with a solid dot at -4, a solid dot at 10, and shading between the two.

o--------------------o
-4 0 10

where the 0 are solid or you could use a [ at -4 and a ] at 10

[----------------------]
-4 0 10


I think that is how interval notation works, but I could be wrong.

Answer 2

well my spacing for -4, 0, 10 didn't come out right, but hopefully you get the idea. -4 at the beginning, 0 towards the middle, and 10 and the end.
