Question

Is the following relation a function?

x y
-1 -2
2 3
3 1
6 -2
Yes
No

Answer 1

do you know how to define a function?

Answer 2

No
the numbers shown are not a repeating order
-1
+1
-2
-8

Answer 3

so the answers is no i get it now @AccidentalAiChan

Answer 4

that's not how you define a function. graph them and do the vertical line test. that will make it obvious

Answer 5

wait so its yes or no

Answer 6

im not giving you the answer lol. graph it and do the vertical line test and think about your x and y points

Answer 7

Actually, there are two ways of doing it.
One way is the vertical line test, the other is simply looking at the x and y table.

Answer 8

yes. but explaining the x and y points is easier once he graphs it

Answer 9

thanks for the answer lol

Answer 10

You're welcome :)

Answer 11

if we give the answer. we are failing you. and his answer isn't correct. because it passes the vertical line test and there aren't any repeating x values

Answer 12

It's easier explaining it like this.

a function is a special relationship between values.
As an example, we will do this one:
y = 2x + 1

Now, let's see which table is the correct one for this function.

X Y
-1 -1
5 9
2 5

or


X Y
-1 -1
5 11
2 5

To find out which represents the function, we need to do the math.

-1 x 2 = -2. Add 1
Y(1) = -1

5 x 2 = 10. Add 1
Y(2) = 11

2 x 2 = 4. Add 1
Y(3) = 5

So now we know that the second table is the correct one.
This is the easiest way to solve it.

Answer 13

so the answer is no

Answer 14

Basically.
Another thing to know is for a function, each number can only be shown once.
if -2 is the output for -1
then it CAN NOT be the output for -6.
This is one important rule that @lonnie455rich forgot to mention, which basically cancels her answer that yes it is a function.

Answer 15

so yes or no

Answer 16

It is the most simple way to tell.
The answer is no.

Answer 17

thanks so much

Answer 18

The domain of the following relation: R: {(3, -2), (1, 2), (-1, -4), (-1, 2)} is

{-1, 1, 3}

{-1, -1, 1, 3}

{-4, -2, 2, 2}

{-4, -2, 2}

Answer 19

You're welcome :)

Answer 20

can you help me in this one too

Answer 21

A.
The domain is your x points.

Answer 22

your smart

Answer 23

I'm majoring in Algebra, so I am pretty well familiar with it

Answer 24

i see that

Answer 25

An ordered pair is

the output (y) value of the relation

the input (x) value of the relation

a set of points that pair input values with output values

x and y values written in the form (x, y)

Answer 26

there can be 2 y but not 2 x's
you aren't thinking correctly at the moment

Answer 27

An ordered pair is the coordinates that you will be graphing.
They are ordered in the format (x , y)

Answer 28

i think its D

Answer 29

Purebred dogs are first assigned the same litter number until they are individually registered with a name. Then the dogs will be assigned a unique registration number with a dog registry. Many people choose to have a microchip implanted in the dog so that it can be read to immediately find the dog's owner.

Which of the following relations is not a function?

(registration number, litter number)

(microchip number, registration number)

(litter number, microchip number)

(microchip number, litter number)

Answer 30

this is my last one

Answer 31

(litter number, microchip number)
Is not a function, because the same litter number can be assigned to multiple dogs with different microchip numbers.
