Ex: Increasing / Decreasing / Relative Extrema from Analyzing a Graph

This video explains how to determine if the graph is a function is increasing or decreasing. It also explains how to determine the relative (local) extrema.

I've been looking for the rest of this video

Mans just tought me more than what my teacher tought me in three class periods

But what would the domain of such a function be in something like interval notation, where not only is -3 included in one set and excluded from another, but also has an area where no points are present in between?

I'm a little confused. at 2:40 you say "were not going to include -2 in the interval because at -2 it changes from increasing to decreasing" however, you do write -2 down in your notation.

[samanthaposchmann]

What about the interval going between 1 and 2 would it be 1.5 instead

you dont have to use infinities while you dont have arrows at the endpoints.
