Correct Answer
A. ([0,1))
Concept
(f(x)=1-\frac{4}{x-2+4}), so (0) is attained but (1) is not. In exams writing such rational expressions in (1-) form is useful.
Why this answer is correct
The correct answer is A. ([0,1)). (f(x)=1-\frac{4}{x-2+4}), so (0) is attained but (1) is not. In exams writing such rational expressions in (1-) form is useful.
Exam Tip
(f(x)=1-\frac{4}{x-2+4}), इसलिए (0) मिलता है पर (1) नहीं मिलता। परीक्षा में ऐसे rational expressions को (1-) रूप में लिखना उपयोगी है।
