Determine the domain and range for the relations. (11, 1), (9,2), (7,3), (5,4)

Hey there! I'm happy to help!

The domain is all of the x-values of a relation and the range is all of the y-values. When you write them out, you order the numbers from least to greatest and put it in brackets.

The domain of our relation is the x-values of these points, which are 11, 9, 7, and 5. The domain is  {5,7,9,11}.

The range is the y-values, which are 1, 2, 3, and 4. So, the range is {1,2,3,4}.

Now you can find the domain and range given a few ordered pairs!

Have a wonderful day!

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
