फलन (f(x)=\frac{2}{(x-1)2}-3) का परिसर क्या है?

What is the range of (f(x)=\frac{2}{(x-1)2}-3)?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

(\frac{2}{(x-1)2}) is always positive but never (0). Therefore the function remains greater than (-3).

Step 2

Why this answer is correct

The correct answer is A. (\(-3,\infty\)). (\frac{2}{(x-1)2}) is always positive but never (0). Therefore the function remains greater than (-3).

Step 3

Exam Tip

(\frac{2}{(x-1)2}) हमेशा धनात्मक है लेकिन (0) नहीं होता। इसलिए फलन (-3) से बड़ा रहता है।
