D) The mean test score will increase by 2.
Step-by-step explanation:
One more and I skskskakakas you
4.25+1.25*m, 5.75+0.75*m
4.25+5.75=10 and 1.25+0.75 = 2 therefore the two expressions are 2m+10
0.5m-1.5 : 4.25+1.25+m-5.75+0.75*m =0.5m-1.5 ( I'm quite sure about this one but I can't think of another answer but this )
Without knowing anything else about 
, neither of these need be true.
Suppose
Then (I) isn't true because, while the limit exists as 
and is equal to 7, we have 
, so is not continuous there.
(II) also true because is not differentiable at 
; that is,
but
which means the derivative does not exist at .
