फलन (f(x)=\frac{1}{x-2-6x+13}) की रेंज क्या है?
What is the range of (f(x)=\frac{1}{x-2-6x+13})?
Explanation opens after your attempt
A. ( \(0,\frac{1}{4}]\)
Concept
The denominator (x-2-6x+13=(x-3)2+4), whose minimum value is (4). So the output is greater than (0) and up to \(\frac{1}{4}\).
Why this answer is correct
The correct answer is A. ( \(0,\frac{1}{4}]\). The denominator (x-2-6x+13=(x-3)2+4), whose minimum value is (4). So the output is greater than (0) and up to \(\frac{1}{4}\).
Exam Tip
हर (x-2-6x+13=(x-3)2+4) है, जिसकी न्यूनतम वैल्यू (4) है। इसलिए output (0) से बड़ा और \(\frac{1}{4}\) तक है।
