The complete square will be 
= 3
Step-by-step explanation:
Given,
or, 
[ by eliminating 2 from both the sides]
To make it square
or, 
[ 
or, = 9-6
or, = 3
Hence the correct option is B
Answer:
coefficient is 1/6
Step-by-step explanation:

This set notation really seems the hard way to exclude a single value. Anyway...
The domain doesn't include where the denominator is zero, 4x + 7 = 0,
x = -7/4
The range doesn't include the asymptotic value, which is
y=2x/4x = 1/2
So we need domain x ≠ -7/4 and range y ≠ 1/2
