फलन (f(x)=\frac{1}{\sqrt{x-2+6x+10}}) का परिसर कौन सा है?

Which is the range of (f(x)=\frac{1}{\sqrt{x-2+6x+10}})?

Explanation opens after your attempt
Correct Answer

A. ((0,1])

Step 1

Concept

Since (x-2+6x+10=(x+3)2+1\ge 1), the denominator has minimum value (1). Therefore (0<f(x)\le 1).

Step 2

Why this answer is correct

The correct answer is A. ((0,1]). Since (x-2+6x+10=(x+3)2+1\ge 1), the denominator has minimum value (1). Therefore (0<f(x)\le 1).

Step 3

Exam Tip

क्योंकि (x-2+6x+10=(x+3)2+1\ge 1), हर का न्यूनतम मान (1) है। इसलिए (0<f(x)\le 1)।
