What is the range of (f(x)=\frac{x^2}{x^2+1})?फलन (f(x)=\frac{x^2}{x^2+1}) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ([0,1))([0,1))
Since (x^2\ge 0), the output can be (0), but it never reaches (1). In exams (\frac{x^2}{x^2+1}=1-\frac{1}{x^2+1}) is useful.(x^2\ge 0) से आउटपुट (0) मिल सकता है, पर (1) कभी नहीं मिलता। परीक्षा में (\frac{x^2}{x^2+1}=1-\frac{1}{x^2+1}) उपयोगी है।
