whats the question ?

- Liv1234

Make a mapping diagram for the relation. {(-2,-6), (0,3), (1,-5), (5,0)}

- hartnn

ok,
so
the arrow that starts from -2 should go to -6

- hartnn

similarly, the arrow starting from 0 goes to 3
and same for others
which option has that property ?

- Liv1234

C? And could you help me with another one? And i LOVE YOUR PROFILE PICTURE!

- hartnn

C is correct :)
sure
yes, I love it too :D

- Liv1234

Okay, I'll post it. And it's kinda funny cause I was watching Dragon Ball this morning, I'm rewatching all the episodes cx

- hartnn

Okay, that's the one. Sorry for the multiple pictures.

- hartnn

which one do you think?

- Liv1234

I was thinking D, but I think I'm wrong.

- hartnn

If you can draw a vertical line anywhere on
a graph so that it hits the graph in more
than one spot, then the graph is NOT a function.

- Liv1234

So, it's not D?

- hartnn

nope, try C

- Liv1234

So, C would be correct?

- hartnn

yes :)

- Liv1234

Omg thank you(:

- Liv1234

Can you help me with one more? I think I have the answer, but I keep getting confused.

- hartnn

sure
ask :)

- Liv1234

Okay, I'll post it here. c:

The one I clicked is the one that I think is right

- hartnn

where would be (3/2, 0) on the graph??
on x axis or on y axis?

- Liv1234

I'm not sure, but it seems like all of the domain and range things are the same. That's what is confusing me

- hartnn

ok,
domain is just the set of all x values
range is the set of y values

- hartnn

and 3/2, 0 will lie in x axis at 3/2 distance from Origin
so what you clicked isn't correct

- Liv1234

My other assumption was that A is the answer.

- hartnn

yes, its A :)

- Liv1234

Omg that was my first guess but I was thrown off. cx thank you! I have to catch up on my overdue work and really wanna watch Dragon Ball when I'm done lol. I appreciate your help.

- hartnn

you're most welcome ^_^
Enjoy the awesome show ;)

- Liv1234

@hartnn I got stuck on a question, could you help?

- Liv1234

##### 1 Attachment

- hartnn

sure

- hartnn

for direct variation
the ratio of y to x is constant

- hartnn

when y = 72, x =18
so y/x = 72/18 = 4

- hartnn

do that for ther set of values and see if you get the ratio as 4 or not

- Liv1234

I'm confused.

- hartnn

24/6 = 4 or not?
216/54 = 4 or not??
648/162 = 4 or not ??

- Liv1234

They are all true.

- Liv1234

Which means the answer is no?

- hartnn

then its a direct varion with k=4 and y = kx :)

- Liv1234

So, it would be A?

- hartnn

yes

- Liv1234

Yay! Would you be able to help me with a couple more?

- hartnn

I can try :)

- Liv1234

Thank you very much(:

##### 1 Attachment

- hartnn

y = kx
y = 2.52, x =8.4
so k = 2.52/8.4 = ... ?

- Liv1234

0.3?

- Liv1234

But, that's not one of the choices though

- hartnn

because thats the value of k :)
y = kx = 2.7*0.3 = ... ?
the answer to that will be in the choices

- Liv1234

0.81 (:

- hartnn

yusss

- Liv1234

I have two more questions, can you still help? (:

- hartnn

yes

- Liv1234

##### 1 Attachment

- hartnn

1 1/3 = 1+1/3 = 4/3

- hartnn

so it would be w = 4/3 t

- Liv1234

So it can't be A or C?

- hartnn

and if you multiply that by 5
we get 20/3 which is just 6 2/3

- hartnn

its B :)

- Liv1234

Yay! Can you help me with one more?

- hartnn

sure

That's the question

- hartnn

y = 5/2 x
so when x =2, y will be 5
which line passes through origin and the point 2,5 ??

- Liv1234

D?

- hartnn

nope
locate 2,5 on the graph

- Liv1234

Oh wait, it kinda looks like it is B.

- Liv1234

Omg wait, is it C?

- hartnn

|dw:1443209456658:dw|
yes its C :)

- Liv1234

Is a 99 in Algebra 2 good? I kinda freaked out about it because I feel like I have to have a 100 in every class.

- hartnn

its too good! :)
Congrats

- Liv1234
