Match List I with List II

List IList II
A. Range of ∣x∣\lvert x\rvertI. (−5,∞)(-5, \infty)
B. Range of 9x2+6x−59x^2 + 6x - 5 for all x≥0x \geq 0II. [0,∞)[0, \infty)
C. Domain of 1x+5\dfrac{1}{\sqrt{x+5}}III. {(1,1),(2,2),(3,3)}\{(1,1), (2,2), (3,3)\}
D. Smallest equivalence relation on Set {1,2,3}\{1,2,3\}IV. [−5,∞)[-5, \infty)

Choose the correct answer from the options given below:

Solution

✅ Correct Option: 3

A: ∣x∣≥0|x| \geq 0, range is [0,∞)[0, \infty) (II).

B: For x≥0x \geq 0, minimum at x=0x = 0 is −5-5, so range is [−5,∞)[-5, \infty) (IV).

C: Need x+5>0x + 5 > 0, so domain is (−5,∞)(-5, \infty) (I).

D: Smallest equivalence relation is the identity {(1,1),(2,2),(3,3)}\{(1,1),(2,2),(3,3)\} (III).
