Quadratic means 2nd degree
I'm thinking
y=ax²
when x=2, y=2
when x=4, y=8
so
2=a2² and
8=a4² or
2=4a and
8=16a
easy
divide first equation by 4 and 2nd by 16 to get
1/2=a
then
A. I would say 1/2 is constant
B. is
I believe the answer is 29
Live Fund receive 
it they sold half thier holding in Marks Brothers.
<u>Solution:</u>
Given: Sale price of Live Fund holding is 5000 dollar
To find: Amount that Live Fund will get if they sell half of their holding in Marks Brothers.

Ratio
if 13.3:9.5=2.52:1.8 then they ar similar
we do
13.3/9.5=2.52/1.8?
1.4/1=1.4/1
ratio is 1.4:1 or invert 1:1.4
answer is 2nd choice
yes; 1:1.4
