[ 1/1Inequality]
Assignment:Find the solution set of inequality √(3x+1) >= √(x-3) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
√ ( 3 * x + 1 ) >= √ ( x - 3 ) (1)
From the definition field of √
3 * x + 1 ≥ 0 (2 )
From the definition field of √
x - 3 ≥ 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 ≥ -1/3
From inequality(3):
x ≥ 3
From inequalities (1) and (2)
x ≥ -1/3 (4)
From inequalities (3) and (4)
x ≥ 3 (5)
The final solution set is :
