Question

is under root 4-y^2 a function of y?

Answer 1

i've been waiting to say this for a looooong time

"go back to the physics section @Shane_B :P"

lol

Answer 2

Yea...I just noticed this one is not actually a function to begin with!

Answer 3

not really. i just wanted to say it

Answer 4

@annie1111: does this look like a function to you?

Answer 5

i dont really know anything about this question. we havent discussed i in class yet :S

Answer 6

This one is simple...it doesn't pass the vertical line test.

Answer 7

@annie1111 your question is this ?
\[\Large x=\sqrt{4-y^2}\]

Answer 8

if its then it is the equation of circle and ,it is not function.

Answer 9

hypothetical question @sami-21 do you believe in the mythical f(y)?

Answer 10

A semicircle anyway

Answer 11

lets make it full circle !
take square of both sides
\[\Large x^2+y^2=4\]

Answer 12

...you never answered my question...

Answer 13

@lgbasallote its just variable.

Answer 14

i have heard of legendary functions such as f(t), f(a), f(b), f(c), etc.

Answer 15

alhough...i cant say i disagree that \(x = \sqrt{4-y^2}\) is not a function of x

Answer 16

I just realized that you never see f(z)....but you do see f(x), f(y)...poor, poor z. Always left out.

Answer 17

another interesting folklore is sami's legendary typing speed

Answer 18

i think he is in Algebra course.wants to know it is function or not. they use vertical line test and the following graph fail vertical line test,s mentioned early by shane.

Answer 19

interestingly the question particularly asked function of y....

Answer 20

but heh what do i know. like i said. i havent learned this stuff in class yet

Answer 21

it was supposed to be learned in Algebra course.

Answer 22

@lgbasallote: didn't you post some DiffEq questions before?

Answer 23

if so, you're taking your classes WAY out of order :P

Answer 24

yeah if i recall, he was playing with some Laplace stuff.

Answer 25

im an advanced reader

Answer 26

lol

Answer 27

im a 44 year old dyslexic

Answer 28

I hated DiffEqs...had a HORRIBLE teacher and although I got an A...that's only because everything was take home. I doubt I learned much of anything :/

Answer 29

yeah i remember your Professor's Laplace equation :)

Answer 30

Parth is Advance reader.

Answer 31

I ride the short bus

Answer 32

parth is a pretentious wannabe lol

Answer 33

seems this still isnt solved huh
