are you able to draw a vertical line anywhere such that it crosses the purple curve more than once?
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)
so it yes?
if you've understood the definition, and are happy with your answer - then go with it
cut i dont
what don't you understand?
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)
if you take ANY point on the x axis - can you find just ONE value for y on the graph?
as if that is on the graph
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?
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?
where the pointy parts are on the wavy line
|dw:1443830184322:dw| show me on this drawing
|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
is it yes?
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
I think you mean "you're mean"
