Answer 2

i think it is A

Answer 3

i think so to but im not sure .3.

Answer 4

ok

Answer 5

What is the range of the relation?

{1, 2, 3, 4}
{1, 2, 3, 4, 6}
{2, 4, 6}
{2, 4}

i think it is d
@endlesslight254

Answer 6

d or b

Answer 7

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

Answer 8

let me look it up im bad at these problems lol

Answer 9

ok

Answer 10

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}

Answer 11

ok now that makes since then it is b

Answer 12

yay ^u^

Answer 13

want the website i found?

Answer 14

no im good thanks though

Answer 15

kk ^u^

Answer 16

For the function f(x) = 2 – 3x, find f(–4).

–10
–5
12
14
other people are saying its 12 but i get -5

Answer 17

ohhh im good at these!

Answer 18

yay

Answer 19

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

Answer 20

oh ok

Answer 21

^u^

Answer 22

i suck at algebra

Answer 23

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

(0, 4)
(0, –4)
(4, 0)
(−4, 0)

Answer 24

its ok i wasnt good at it either

Answer 25

i think it is b

Answer 26

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

Answer 27

im surprised i even know this stuff

Answer 42

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

Answer 43

ok

Answer 44

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

Answer 45

i think it is b

Answer 46

its a or b ^u^

Answer 47

its a

Answer 48

but other people say it is d

Answer 49

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

Answer 50

yeah thats true ill try d

Answer 51

alright ^u^

i hope u pass :o

Answer 68

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
