f(x) = y. When x is 4... y is.. ?
wouldnt X be -4 and y be 4?
Well, similar to your last one. F(x) is the normal format. So, in this case, X = 4. Go along the X line until you reach 4. Then, go up until you hit the line. This, is where your Y line is, and your answer.
so its C?
Remember, a function gives us what's called a "dependent variable" from an"independent variable". If x is 4, it doesn't mean y will be 4. So f(x) does not equal x. f(4) is not necessarily 4. f(4) will be the y coordinate (4,y)
If Y = 4 then X would equal 0.
wait.. no its A? -4?
"X = 4. Go along the X line until you reach 4. Then, go up until you hit the line. This, is where your Y line is, and your answer."
As monkiwi said. Go to the value of x on the graph. What is the y value at that point?
No, it isn't -4. Look at where the points intersect.
If Y = -4 X = -8
so i was right the first time.. its 4.. right?
its not 4?? how is it not? the y meets at the 4??
we are given f(4) where x = 4.... go to where x = 4 it's like ... (4, y) who is the y in here?
wow thanks for giving out the direct answer -_-!
Remember, your answer can only include somewhere that's actually a point on the graph (in this case the infinite points contained in the line)
MY *************************************!!!! I AM THE MOST IDIOT PERSON!! I SWEAR.. u guys prob think im 3.. ugh! its 8..
Not really direct answer...
dont tell me its not 8??? if its not 8.. dear .. my brain
if you think that's tough, check out all the questions I've asked >:D
ok.. well my brain just xploded.. ugh who do i give medal too?? u all helped.. ALOT..
No one :)
yeah make it fair.. no one
wait until next question then anyone can free for all.
let me do this. one sec
what does that supposed to mean?
Oh I see! Hey man I'm getting there slowly but surely :P
what is F(5) A. –8 B. 0 C. 2 D. 5 http://static.k12.com/calms_media/media/1417000_1417500/1417260/1/35db032be3c6dfeeebcc053d76b1a6f3345aa510/MS_PA_130905_170066.jpg
first to answer ill medal.. plis explain :D
I'm out. This is too easy... I wanna do ODEs
plis.. cmon! D:
just answer.. cmon!! D::::
the smart ones think im dumb.. and im a straight A student.. YIKEs
fineeeeeeeeeeeee F(x) -> F(5) implies that x = 5. just find where x = 5 in your chart and you will have y
im sorry.. Im really trying here. you said the 5. and on the chart it has a 2 by it..
I said f(x) was the standard notation of a function . If we have something like f(5).. then .. I said x = 5 because f(x) -> f(5) implies that x = 5. on the x chart LOOK UP 5
i gave u medal.. sorry for wasting ur time.. :/
