फलन (f(x)=-\frac{3}{(x+1)2}+2) का परिसर क्या है?
What is the range of (f(x)=-\frac{3}{(x+1)2}+2)?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,2\))
Concept
(-\frac{3}{(x+1)2}) is always negative and never becomes (0). So (f(x)) is always less than (2).
Why this answer is correct
The correct answer is A. (\(-\infty,2\)). (-\frac{3}{(x+1)2}) is always negative and never becomes (0). So (f(x)) is always less than (2).
Exam Tip
(-\frac{3}{(x+1)2}) हमेशा ऋणात्मक होता है और (0) नहीं बनता। इसलिए (f(x)) हमेशा (2) से कम है।
