10-28 Class notes

Set notation:  If you are asked to describe or list a domain or range, use curly brackets {  }

For the example we did in class from page 76, item 3a, the domain is { -5, 0, 4 }

For the example on page 78, item 1a, the domain is { x > -5 and x < 5 }.
The range is { y > -4 and y < 4 }.


There will be a quiz on Tuesday 11-1.
