What is the range of (f(x)=\frac{x^2}{x^2+4})?फलन (f(x)=\frac{x^2}{x^2+4}) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([0,1))([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.(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।
