फलन (f(x)=\frac{3}{x-2+2}-5) की रेंज क्या है?
What is the range of (f(x)=\frac{3}{x-2+2}-5)?
Explanation opens after your attempt
A. (\(-5,-\frac{7}{2}]\)
Concept
The range of \(\frac{3}{x^2+2}\) is ( \(0,\frac{3}{2}]\). Adding (-5) gives (\(-5,-\frac{7}{2}]\).
Why this answer is correct
The correct answer is A. (\(-5,-\frac{7}{2}]\). The range of \(\frac{3}{x^2+2}\) is ( \(0,\frac{3}{2}]\). Adding (-5) gives (\(-5,-\frac{7}{2}]\).
Exam Tip
\(\frac{3}{x^2+2}\) की रेंज ( \(0,\frac{3}{2}]\) है। इसमें (-5) जोड़ने पर (\(-5,-\frac{7}{2}]\) मिलता है।
