What is the domain of (f(x)=\sqrt{\frac{x-1}{x+2}})?फलन (f(x)=\sqrt{\frac{x-1}{x+2}}) का प्रांत क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( (-\infty,-2)\cup[1,\infty) )( (-\infty,-2)\cup[1,\infty) )
The expression inside the square root must satisfy (\frac{x-1}{x+2}\ge 0) and (x\ne -2). A sign chart gives (x<-2) or (x\ge 1).वर्गमूल के अंदर (\frac{x-1}{x+2}\ge 0) और (x\ne -2) चाहिए। संकेत सारणी से (x<-2) या (x\ge 1) मिलता है।
