Question

Does the table below represent a function?
yes
no

Answer 1

what do you think?

Answer 2

I think it might be

Answer 3

Either it is or it is not a function.

What would make it a function?

Answer 4

well a function is like a relation between inputs right

Answer 5

Yes, but it is a special relation. It is a relation such that for each input, there is one and only one outout. Look at the inputs. Is there only one output for that input?

Answer 6

well like they all go down so that's a way they relate um I need to g=figure out how much each goes down

Answer 7

12 they all go down 12

Answer 8

I think its a function

Answer 9

It has nothing to do whether it goes down two, ten, or a million.

It had to do with the idea that for each input there is one output, regardless of what that output is.

Answer 10

can you explain the output more like what is the output

Answer 11

Take y = 2x + 3

Let's put in numbers for x.

If x = 2, then the output is y = 7
If x = 0, then y= 3

So we put in a number for x, where x is the input, and out comes a number for y. y is called the output.

Answer 12

Look at the table. Is this a function?

Answer 13

how do you get the output do you multiply

Answer 14

It makes no difference how I got the output. Just look at the table, and determine whether that relation is a function or is not a function.
