What is the range of the relation?
{(1, 2), (2, 4), (3, 1), (4, 3)}
{1, 2, 3, 4}
{1, 2, 3, 4, 6}
{2, 4, 6}
{2, 4}
i think it is d

d or b

ok what does it mean when its asking to find the range of a relation i have a problem on that and its hard to understand it

- anonymous

let me look it up im bad at these problems lol

- shadow13

ok

i hope this helps love <3
State the domain and range of the following relation. Is the relation a function?
{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}
The above list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication:
domain: {2, 3, 4, 6}
range: {–3, –1, 3, 6}

- shadow13

ok now that makes since then it is b

- anonymous

yay ^u^

- anonymous

want the website i found?

- shadow13

no im good thanks though

- anonymous

kk ^u^

For the function f(x) = 2 – 3x, find f(–4).
–10
–5
12
14
other people are saying its 12 but i get -5

- anonymous

ohhh im good at these!

- shadow13

yay

- anonymous

F(-4)=2-3(-4)
f(-4)=2--12
f(-4)=2+12
f(-4)=14
the answer is 14

- shadow13

oh ok

- anonymous

^u^

- shadow13

i suck at algebra

What is the turning point of the graph of f(x) = |x – 4| ?
(0, 4)
(0, –4)
(4, 0)
(−4, 0)

- anonymous

its ok i wasnt good at it either

- shadow13

i think it is b

- anonymous

x - 4 = 0
x = 4
f(4) = |x - 4|
turning point : (4, 0)

- anonymous

im surprised i even know this stuff

Which is the graph of the function g(x) = |x – 3|? it needs to be a gragh and i think it is d but not sure

- shadow13

oops tomany

- anonymous

XD

- shadow13

can u help though there v graphed and its up or down

- anonymous

i can try could u post the graph??

- shadow13

it wont let me

which one at the top is the question?

- shadow13

Which is the graph of the function g(x) = |x – 3|? this is the question for those answers

- anonymous

im bad at this question put what ever u think it is love ^u^

- shadow13

ok

Which is the direct linear variation equation for the relationship?
y varies directly with x and y = 10 when x = 2.
y = 2x + 6
y = x + 8
y = x – 8
y = 5x

- shadow13

i think it is b

- anonymous

its a or b ^u^

- shadow13

its a

- shadow13

but other people say it is d

- anonymous

then its probably d cause of the 10 but then again it also could be a

- shadow13

yeah thats true ill try d

- anonymous

alright ^u^

Which relationship shows a quadratic variation?
A X: 2,3,4,5
f(x): 1,4,9,16
b. x: 1,2,3,4
f(x):2,8,18,32
c. x:1,2.3,4
f(x): 2,5,10,17
d. x: 1,2,3,4
f(x): 4,3,2,1

- shadow13

i think it is a

- anonymous

yea it must be a :3

- shadow13

ok

- shadow13

Which is the quadratic variation equation for the relationship?
y varies directly with x2 and y = 36 when x = 3.
y = x2
y = x2
y = 4x2
y = 12x2
think it is B

- anonymous

its b or c

- anonymous

ur bro got a account and now asking me to help him XD

- shadow13

dont do it

- anonymous

im not gonna help him when im helping u <3

Which relationship shows an inverse variation?
A.x. 2,3,4,5
f(x):1,4,9,16
B. x.1,223,4
f(x): 2,8,18,32
C.x:1,2,3,4
f(x):4,3,2,1
D.x: 2,4,6,8
f(x): 12,6,4,3
i dont know

- anonymous

idk either O.O

- shadow13

if i took a wild guess i would pic b

- anonymous

same lol

- anonymous

are u doing a math test or a assignment?

- shadow13

math test i have two more

- anonymous

i hope u pass :o

y varies inversely with x and y = 8 when x = 2.
Which is the inverse variation equation for the relationship?
(Points : 4)
y = 16x
y=16/x
y = 2x
y = x + 2
i think it is c

- shadow13

i hope so too

- anonymous

its c ^u^

- shadow13

yay i did it

- shadow13

If f(x) varies directly with x and f(x) = 50 when x = –10, then what is f(x) when x = 15
–150
–75
–30
–5
i think it is B

- anonymous

yay im glad u got that question right :D

- shadow13

why

- anonymous

cause that means ur smart silly ^u^

- shadow13

o ok

- anonymous

^u^

- shadow13

i got more quiez and exams and assinments

- shadow13
