are you able to draw a vertical line anywhere such that it crosses the purple curve more than once?

yesw

- jim_thompson5910

where?

- Thats_Kyy

nowhere

- MrNood

if each value of x has only ONE corresponding value of y then it IS a function
(this is another way of looking at @jim_thompson5910 's answer)

- Thats_Kyy

so it yes?

- MrNood

if you've understood the definition, and are happy with your answer - then go with it

- Thats_Kyy

cut i dont

- MrNood

what don't you understand?

- Thats_Kyy

everything

- Thats_Kyy

its no

- MrNood

hmmm - that's a LOT to explain in a simple text box.
read my definition again:
if each value of x has only ONE corresponding value of y then it IS a function
what do oyu not understand about that
(btw it IS either yes or no - so you're almost there)

- MrNood

if you take ANY point on the x axis - can you find just ONE value for y on the graph?

- Thats_Kyy

as if that is on the graph

@Nnesha

- MrNood

look at the graph you were given (the wavy line)
go along the x axis and choose ANY point you like.
is there just one point on the wavy line that corresponds to the value on the x axis?

- Thats_Kyy

ok

- Thats_Kyy

no

- Thats_Kyy

their isn't

- MrNood

can you tell me the point on the x axis that you have chosen where there is more than 1 value on the wavy line?

- Thats_Kyy

where the pointy parts are on the wavy line

- MrNood

show me on this drawing

- Thats_Kyy

|dw:1443830257544:dw|

- MrNood

|dw:1443830272353:dw|
each point htat you drew is the only point corresponding to the value on the x axis.
It seems to me that you don't have th ebackground knowledge to answer this question.
You need to revise your learning on graphs and how to read them, and THEN look at the definition of a function I gave above

- Thats_Kyy

is it yes?

- MrNood

If I tell you YES or NO you will still not have any understanding of WHY that it the answer - so the answer is useless to you

- Thats_Kyy

your mean

- MrNood

I think you mean "you're mean"
