Correct Answer

A. (k>-3)

Step 1

Concept

For decay, the effective coefficient of (x) must be negative. From (-(k+3)<0), (k>-3).

Step 2

Why this answer is correct

The correct answer is A. (k>-3). For decay, the effective coefficient of (x) must be negative. From (-(k+3)<0), (k>-3).

Step 3

Exam Tip

क्षय के लिए (x) का प्रभावी गुणांक ऋणात्मक चाहिए। (-(k+3)<0) से (k>-3) मिलता है।
