Look at the graphs below

A set is a collection of things. A lot of times in math, we'll use set notation when our variable could equal a whole lot of different numbers. (This usually is the case with inequalities.)

Use words to describe the conditions for x!

Interval notation is a simpler way to write set notation using parentheses and brackets.

In one color, highlight all of the words that mean domain In another color, highlight all of the words that mean range

To find the domain, highlight all of the graphs INPUTS on the X-AXIS Domain:

To find the range, highlight all of the graphs OUTPUTS on the Y-AXIS Range:

Domain: Range:

With a partner match the Domain/Range to the appropriate graph. When completed turn in to Mrs. Sawyer and begin your homework!

On a sheet of paper complete the following: 1)What does “Domain” mean? 2)What does “Range” mean? 3)Tell me one thing you learned today. (other than 1 & 2) 4)Which parts of today’s lesson are you still struggling with?
