Answer 4

HELP bwaaahhahaaaaaa

Answer 5

first, direct variation means we have an equation
y = k x
where k is a constant.

however, "quadratic variation" is a fancy way to say "use x^2" instead of x
in other words, direction variation with the square of x:
y = k x^2

the next step is to find k.
to do that, use one of the (x,y) pairs in the table.

can you do that ?

Answer 6

can you pick an (x,y) pair from the table ?

Answer 7

2 24

Answer 8

is the answer 6

Answer 10

@amistre64

Answer 11

with 2,24
that is, x=2 and y=24
you use those numbers instead of "x" and "y" in
y = k x^2

in other words, erase "y" and put 24 in its place
do the same for x: erase the x, and put in 2 in its place

what do you get ?

Answer 12

6

Answer 13

you get
24= k 2^2

2^2 means 2*2 , which is 4

24 = k*4

to find k , divide both sides by 4

Answer 14

so its 6

Answer 15

@phi

Answer 16

k is 6

you can test it. the equation is
y = 6 x^2

if this is correct, then if we "put in" x, we should "get out" the correct y

Answer 17

For example, for x=3, the equation says
y = 6*3^2 or
y= 6*3*3
and that simplifies to
y= 54
which matches the table. Looks good.

Answer 18

so its 6
