Question 15659: find the domain for f(x)=(2x+1)/(x+6).
Answer by venugopalramana(3286)   (Show Source):
You can put this solution on YOUR website! domain for f(x)=(2x+1)/(x+6).
certain operations in maths like division by zero ,square root of a negative numbers are not allowed .
so by domain of a function we mean such values of independent variable ( usually x ) which make the function exist with permissible operations.
we have to look at denominator here .it has x+6 ..it should not be zero
so the domain is all values of x in the real number set except x=-6
