Assignment:Find the solution set of inequality ln(2-X) ≥0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
ln ( 2 - X ) ≥0 (1)
From the definition field of ln
2 - x > 0 (2 )
From inequality(1):
X ≤ 1
From inequality(2):
X < 2
From inequalities (1) and (2)
X ≤ 1 (3)
The final solution set is :
X ≤ 1Your problem has not been solved here? Please take a look at the hot problems !
