If (f(x)=\frac{x}{x-2}) and (g(x)=\frac{2}{x-2}), what is ((f-g)(x)) and its domain?यदि (f(x)=\frac{x}{x-2}) और (g(x)=\frac{2}{x-2}) हैं, तो ((f-g)(x)) किसके बराबर है और उसका प्रांत क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1), (x\ne 2)(1), (x\ne 2)
((f-g)(x)=\frac{x-2}{x-2}=1), but (x=2) is outside the original domain. Keep restrictions even after simplification.((f-g)(x)=\frac{x-2}{x-2}=1), पर (x=2) मूल प्रांत से बाहर है। सरलीकरण के बाद भी प्रतिबंध याद रखें।
