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:

i hope this : )

thus, the first answer choice, y = sec x, is the correct one
