[ 1/1Inequality]
Assignment:Find the solution set of inequality lg(x+6)
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
lg ( x + 6 ) < lg 3 * x - lg ( x - 2 ) (1)
From the definition field of lg
x + 6 > 0 (2 )
From the definition field of lg
x - 2 > 0 (3 )
From inequality(1):
x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequality(2):
x > -6
From inequality(3):
x > 2
From inequalities (1) and (2)
x > -6 (4)
From inequalities (3) and (4)
x > 2 (5)
The final solution set is :
