यदि (f(x)=x-2) और (g(x)=2x) हैं, तो ((fg)(x)) का परास क्या है?
If (f(x)=x-2) and (g(x)=2x), what is the range of ((fg)(x))?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}\)
Concept
((fg)(x)=2x-3), whose range is all real numbers. An odd-degree polynomial often covers \(\mathbb{R}\).
Why this answer is correct
The correct answer is A. \(\mathbb{R}\). ((fg)(x)=2x-3), whose range is all real numbers. An odd-degree polynomial often covers \(\mathbb{R}\).
Exam Tip
((fg)(x)=2x-3), जिसका परास सभी वास्तविक संख्याएं है। विषम घात वाला बहुपद अक्सर \(\mathbb{R}\) तक जाता है।
