Created by Sal Khan and Monterey Institute for Technology and Education. Best regards, ST(5 votes). We have, it's defined for a certain-- if this was a whole relationship, then the entire domain is just the numbers 1, 2-- actually just the numbers 1 and 2.

Relations And Functions Unit
Pressing 5, always a Pepsi-Cola. But for the -4 the range is -3 so i did not put that in.... so will it will not be a function because -4 will have to pair up with -3. I just wanted to ask because one of my teachers told me that the range was the x axis, and this has really confused me. The output value only occurs once in the collection of all possible outputs but two (or more) inputs could map to that output. It usually helps if you simplify your equation as much as possible first, and write it in the order ax^2 + bx + c. So you have -x^2 + 6x -8. And because there's this confusion, this is not a function. And then finally-- I'll do this in a color that I haven't used yet, although I've used almost all of them-- we have 3 is mapped to 8. It can only map to one member of the range. You give me 2, it definitely maps to 2 as well. Unit 3 - Relations and Functions Flashcards. Or you could have a positive 3. Then we have negative 2-- we'll do that in a different color-- we have negative 2 is associated with 4. So you don't know if you output 4 or you output 6. Now with that out of the way, let's actually try to tackle the problem right over here.

If there is more than one output for x, it is not a function. It should just be this ordered pair right over here. Hi, this isn't a homework question. Unit 2 homework 1 relations and functions. Is there a word for the thing that is a relation but not a function? So once again, I'll draw a domain over here, and I do this big, fuzzy cloud-looking thing to show you that I'm not showing you all of the things in the domain. Let's say that 2 is associated with, let's say that 2 is associated with negative 3.

The five buttons still have a RELATION to the five products. The answer is (4-x)(x-2)(7 votes). Unit 3 relations and functions answer key page 65. Now the relation can also say, hey, maybe if I have 2, maybe that is associated with 2 as well. If the f(x)=2x+1 and the input is 1 how it gives me two outputs it supposes to be 3 only? Can you give me an example, please? Let me try to express this in a less abstract way than Sal did, then maybe you will get the idea. And it's a fairly straightforward idea.
Unit 2 Homework 1 Relations And Functions
So this relation is both a-- it's obviously a relation-- but it is also a function. If you graph the points, you get something that looks like a tilted N, but if you do the vertical line test, it proves it is a function. We have negative 2 is mapped to 6. We call that the domain. So there is only one domain for a given relation over a given range. So the question here, is this a function?
So we also created an association with 1 with the number 4. It could be either one. So before we even attempt to do this problem, right here, let's just remind ourselves what a relation is and what type of relations can be functions. If 2 and 7 in the domain both go into 3 in the range. The ordered list of items is obtained by combining the sublists of one item in the order they occur.
