फलन (f(x)=\frac{x-1}{x-2+2x-3}) का डोमेन क्या है?
What is the domain of (f(x)=\frac{x-1}{x-2+2x-3})?
Explanation opens after your attempt
A. \(\mathbb{R}\setminus{1,-3}\)
Concept
The denominator (x-2+2x-3=(x+3)(x-1)) removes (x=-3) and (x=1). In exams factorize the denominator.
Why this answer is correct
The correct answer is A. \(\mathbb{R}\setminus{1,-3}\). The denominator (x-2+2x-3=(x+3)(x-1)) removes (x=-3) and (x=1). In exams factorize the denominator.
Exam Tip
हर (x-2+2x-3=(x+3)(x-1)) से (x=-3) और (x=1) हटेंगे। परीक्षा में हर को गुणनखंड करें।
