यदि (f(x)=x-2-3x+2) और (g(x)=x-1) हों, तो (\left\(\frac{f}{g}\right\)(x)) का सही रूप क्या होगा?
If (f(x)=x-2-3x+2) and (g(x)=x-1), what is the correct form of (\left\(\frac{f}{g}\right\)(x))?
Explanation opens after your attempt
A. \(x-2,\ x\ne 1\)
Concept
(x-2-3x+2=(x-1)(x-2)), but (x=1) is excluded. Always write the domain restriction with a simplified form.
Why this answer is correct
The correct answer is A. \(x-2,\ x\ne 1\). (x-2-3x+2=(x-1)(x-2)), but (x=1) is excluded. Always write the domain restriction with a simplified form.
Exam Tip
(x-2-3x+2=(x-1)(x-2)), पर (x=1) हटेगा। सरलीकृत रूप के साथ प्रांत प्रतिबंध लिखना जरूरी है।
