Answer:
Table J
Step-by-step explanation:
A direct variation is a simple relationship between x and y.
When you are looking for the direct relationship you should use the formula for it y=kx, or you could just divide y over x (
).
<em><u>Analysing Table F:</u></em>
The relationship between x and y is 4.

The origin is fine and doesn't ruin the relationship.
<em><u>Analysing Table G:</u></em>
The relationship between x and y is 5.

<em><u>Analysing Table H:</u></em>
The relationship between x and y is
.

Like I said before the origin doesn't ruin the relationship so it's fine.
<em><u>Analysing Table J:</u></em>
This one doesn't have a direct relationship between x and y.



For
, substitute "
" for each occurrence of "
".

Answer: Option A -439
(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
