Can someone explain to me how to do these questions? Will fan and medal! a. Give an example of a relation with at least 4 ordered pairs b. What is the domain of your relation? c. What is the range of your relation? d. Is your relation a function? Why or why not? Thank you so very much!
You need to make up some numbers! It's asking you for a relation with 4 ordered pairs. So you would need to make up 4 ordered pairs to answer these questions. For example: (1,2) (3,4) (5,6) (7,8) Those are my four ordered pairs. To find your domain you need to look at all your X values. Your domain would be all of your X values in a row! You can write it like this: domain {1, 3, 5, 7} Your range is all of the Y values. You do the same thing you did for the domain, like this: range {2, 4, 6, 8} Functions mean that the X values only go to ONE Y value. The set that I gave you is a function because there are no X values that go to two Y values. Here is an example of a set that is NOT a function: (1,2) (3,4) (3,7) (5,6) The X value 3 here meets with both y=4 and y=7. That is not a function. Hope I helped!
Thank you so much! You helped so much! (:
No problem! :)
