फलन (f(x)=x-3) का प्रांत और परिसर क्या है?
What are the domain and range of (f(x)=x-3)?
Explanation opens after your attempt
Correct Answer
A. प्रांत \(\mathbb{R}\), परिसर \(\mathbb{R}\)Domain \(\mathbb{R}\), range \(\mathbb{R}\)
Concept
The cubic function is defined for every real (x) and can take every real value. Hence both are \(\mathbb{R}\).
Why this answer is correct
The correct answer is A. प्रांत \(\mathbb{R}\), परिसर \(\mathbb{R}\) / Domain \(\mathbb{R}\), range \(\mathbb{R}\). The cubic function is defined for every real (x) and can take every real value. Hence both are \(\mathbb{R}\).
Exam Tip
घन फलन हर वास्तविक (x) के लिए परिभाषित है और हर वास्तविक मान ले सकता है। इसलिए दोनों \(\mathbb{R}\) हैं।
