If (f:\mathbb{R}\to\mathbb{R}), (f(x)=x^3+x^2), why is it not one-one on all (\mathbb{R})?यदि (f:\mathbb{R}\to\mathbb{R}), (f(x)=x^3+x^2) है, तो यह पूरे (\mathbb{R}) पर एकैकी क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because (f(0)=f(-1))क्योंकि (f(0)=f(-1))
Step 1: Test the function at two different values. Step 2: (f(0)=0) and (f(-1)=(-1)^3+(-1)^2=0), while (0\ne -1). Step 3: One pair of distinct inputs with the same image breaks one-one nature on the whole domain.चरण 1: दो अलग मानों पर फलन का मान जांचें। चरण 2: (f(0)=0) और (f(-1)=(-1)^3+(-1)^2=0), जबकि (0\ne -1)। चरण 3: एक ही प्रतिबिंब देने वाली जोड़ी मिलते ही पूरे प्रांत पर एकैकीपन टूट जाता है।
