To check for continuity at the edges of each piece, you need to consider the limit as 
approaches the edges. For example,
has two pieces, 
and 
, both of which are continuous by themselves on the provided intervals. In order for 
to be continuous everywhere, we need to have
By definition of , we have 
, and the limits are
The limits match, so is continuous.
For the others: Each of the individual pieces of 
are continuous functions on their domains, so you just need to check the value of each piece at the edge of each subinterval.
Answer:
First of all you need to know the 
it's equal to 2 and
which is the number is between 1 and 2 and between that number there maybe the possibilities of above 0.5 or under 0.5
After that Figure out which one was bigger? 
or 
? The answer is 
and also near to 
so it should be above 0.5 .
So we know that is between 1 and 1.5.
Hopes that information was help you a lot
We see from the attached, that kite area = product of the diagonals / 2
The diagonals could be 12 by 8 or
6 by 16 or
3 by 32, etc
It cannot be narrowed down any further.
1st one is true and second one false.
