Find the Domain log of x+2 = log of 3x-3
Problem
Solution
Identify the constraints for the logarithmic functions, as the argument of a logarithm must be strictly greater than zero.
Set up the inequality for the first term:
Solve for
x in the first inequality:
Set up the inequality for the second term:
Solve for
x in the second inequality:
Determine the intersection of the two conditions
x>−2 andx>1 to find the values ofx for which both logarithms are defined.Conclude that since
1>−2 the intersection isx>1
