फलन (f(x)=\sqrt{x+3}) का प्रांत क्या है?

What is the domain of (f(x)=\sqrt{x+3})?

Explanation opens after your attempt
Correct Answer

A. \([-3,\infty\))

Step 1

Concept

The expression inside the square root must satisfy \(x+3 \ge 0\). Therefore \(x \ge -3\).

Step 2

Why this answer is correct

The correct answer is A. \([-3,\infty\)). The expression inside the square root must satisfy \(x+3 \ge 0\). Therefore \(x \ge -3\).

Step 3

Exam Tip

वर्गमूल के अंदर \(x+3 \ge 0\) होना चाहिए। इसलिए \(x \ge -3\) है।
