फलन (f(x)=\log_2\(x^2-5x+6\)) का प्रांत क्या है?
What is the domain of (f(x)=\log_2\(x^2-5x+6\))?
Explanation opens after your attempt
A. (\(-\infty,2\)\cup\(3,\infty\))
Concept
For a logarithm, \(x^2-5x+6>0\) is needed. Since ((x-2)(x-3)>0), (x<2) or (x>3).
Why this answer is correct
The correct answer is A. (\(-\infty,2\)\cup\(3,\infty\)). For a logarithm, \(x^2-5x+6>0\) is needed. Since ((x-2)(x-3)>0), (x<2) or (x>3).
Exam Tip
लघुगणक के लिए \(x^2-5x+6>0\) चाहिए। ((x-2)(x-3)>0), इसलिए (x<2) या (x>3)।
