What is the domain of (f(x)=\sqrt{\frac{x+5}{9-x}})?
Explanation opens after your attempt
A. ([-5,9))
Concept
The condition is \(\frac{x+5}{9-x}\ge0\) and \(x\ne9\). A sign table gives the correct domain ([-5,9)).
Why this answer is correct
The correct answer is A. ([-5,9)). The condition is \(\frac{x+5}{9-x}\ge0\) and \(x\ne9\). A sign table gives the correct domain ([-5,9)).
Exam Tip
शर्त \(\frac{x+5}{9-x}\ge0\) और \(x\ne9\) है। संकेत तालिका से ([-5,9)) सही डोमेन मिलता है।
