If (f:[0,\infty)\to\mathbb{R}), where (f(x)=\sqrt{x}), why is (f) not onto?यदि (f:[0,\infty)\to\mathbb{R}) जहाँ (f(x)=\sqrt{x}), तो (f) आच्छादी क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because negative real values are not attainedक्योंकि ऋणात्मक वास्तविक मान नहीं मिलते
Step 1: (\sqrt{x}) is always non-negative. Step 2: The codomain (\mathbb{R}) includes negative values, which are not attained. Step 3: Remember that the range of the square root function is ([0,\infty)).चरण 1: (\sqrt{x}) का मान हमेशा (0) या उससे बड़ा होता है। चरण 2: सहप्रांत (\mathbb{R}) में ऋणात्मक मान भी हैं, जो नहीं मिलते। चरण 3: मूल फलन में परिसर ([0,\infty)) याद रखें।
