Question

Graph the relation {(5, 0), (0, 5), (5, 1), (1, 5)}. Is it a function? Why or why not?

Answer 1

if it's a function, that means that every input hads only one output. ususally, the first number in the ordered pair is the input and the second is the output.

Answer 2

y is not a function of x because two different x's give different y's ((5,0) and (5,1) if x is 5 then y can't both be 0 and 1. So I'd say no not a function.

Answer 3

these are my choices.
A.Yes, it passes the horizontal-line test.
B. No, it does not pass the horizontal-line test
C. Yes, it passes the vertical-line test.
D.No, it does not pass the vertical-line test..

Answer 4

@Drahgnus please read the code of conduct. don't just give out answers. instead help lead them to a place of understanding.

Answer 5

doesn't pass the vertical line test because at x = 1 there are two y's above it. Btw pgpilot archer vice is awesome

Answer 6

oh lol didn't know that sorry first 20 minutes on this site

Answer 7

yeah, i can't wait!

Answer 8

lol its ok. so my answer would be C.??

Answer 9

no worries, how did you get a score of 42 in 10 minutes?

Answer 10

nope answer is not C.

Answer 11

ohh...? does it pass the vertical??

Answer 12

so snap so it would be D. my bad

Answer 13

you tell me, what does it mean to pass the vertical line test?

Answer 14

I've answered like 20 questions they're all kinda simple here, I'm trying to get an answer to differential equation question. Look that type of math up and thats how :P Aerospace engineering ;)

Imagine putting a vertical line at x = 1, does it hit more than one y when you do that?

Answer 15

funny, i have a degree in math and didn't get points that quick.

Answer 16

what kind of diffy q?

Answer 17

I wish I could both of you guys medals.. sorry I cant though

Answer 18

Give it to pg

Answer 19

did you get your question figured out, @PeytonPerez372 ?

Answer 20

LANA!!!!

Answer 25

SPLOOOSH

Answer 26

Bloody mary, blessed are you among wingspantails. Pray for me now in the hour of my death, which I hope is soon. Amen.

Answer 27

oh for my differential equation.. you have a degree in math? that might help... okay so its a homogenous differential, so youre supposed to use u = y/x
y' = y/x + x / [(x^2 * y)^1/3 + (xy)^1/2 + x ]

Answer 28

i've literally waited my whole life to say these words...
I'm comandeering this AIRBOAT!!!

Answer 29

hahahaha who do i remind you of?! burt reynolds in what?!

Answer 30

okay and what did you get after subbing?

Answer 31

GATOR

Answer 32

oh wait, the one before had the airboats...
WHITE LIGHTNING!

Answer 33

I can't get it in a form of y/x that's my problem, I know in the end the y' = u + xu' and then the right side the first part is u + ... its just a mess I don't even know, I've tried dividing by xy^1/2 but it didn't look promising.. tried dividing by y.. just not working for me :\

Answer 34

okay, hold on a sec...

Answer 35

and I think the reason I received points so fast was because I just gave them the answer, didn't show any work and did that to like 30 simple problems lol.

Answer 36

thanks a lot :D if you want I can link you to my question after so you can get a medal

Answer 37

so did you get \[y'=\frac{u'x^2+y}{x}\]

Answer 38

you guys are like trolling my question lol

Answer 39

sorry this should be a link to my question http://openstudy.com/users/drahgnus#/updates/52d979fae4b05ee05437f785

Answer 40

sorry @PeytonPerez372
