<PRE><B>Question 30529</B>
y= 3x-7/2x+8  ----(1)
Since division by zero is not defined
(2x+8) SHOULD NOT BE ZERO
And (2x+8)willbe zero then 2x = -8 which implies x = -82 = -4
Therefore for (1) to exist, x SHOULD NOT BE (-4)
Therefore (1) is defined for all x excepting (-4)
Therefore our answer set is 
the complement of the singleton set {-4} in R the real number system
