Hey where is the graph for Function B?
Answer with Step-by-step explanation:
We are given that A, B and C are subsets of universal set U.
We have to prove that

Proof:
Let x
Then
and 
When
then
but 
Therefore,
but 
Hence, it is true.
Conversely , Let
but 
Then
and
When
then 
Therefor,
Hence, the statement is true.
18 = (240/100) x what;
what = 18 x (100/240);
what = 1800/240;
what = 7.5;
