यदि (f(x)=\frac{1}{x}) और (g(x)=x-2) हों, तो ((fg)(x)) को सरल करें।
If (f(x)=\frac{1}{x}) and (g(x)=x-2), simplify ((fg)(x)).
Explanation opens after your attempt
Correct Answer
A. (x), \(x\ne 0\)
Concept
((fg)(x)=\frac{1}{x}\cdot x-2=x), but the original domain keeps \(x\ne 0\). Restrictions do not disappear after simplification.
Why this answer is correct
The correct answer is A. (x), \(x\ne 0\). ((fg)(x)=\frac{1}{x}\cdot x-2=x), but the original domain keeps \(x\ne 0\). Restrictions do not disappear after simplification.
Exam Tip
((fg)(x)=\frac{1}{x}\cdot x-2=x), पर मूल डोमेन में \(x\ne 0\) रहेगा। सरल करने से हटे प्रतिबंध वापस नहीं आते।
