Paragraph for below question
नीचे दिए गए प्रश्न के लिए अनुच्छेद

Consider that f:AB

(i) If f(x) is one-one then f(x1) = f(x2) ⇔ x1 = x2 or f ′(x) > 0 or f ′(x) < 0.
(ii) If f(x) is onto then range of f(x) is B.

Choose the correct answer.

f:AB पर विचार कीजिए।

(i) यदि f(x) एकैकी है तब f(x1) = f(x2) ⇔ x1 = x2 या f ′(x) > 0 या f ′(x) < 0
(ii) यदि f(x) आच्छादक है तब f(x) का परिसर B है।

सही उत्तर का चयन कीजिए।

Q. f:RB, if f(x) = sinx and given f(x) is an onto function, then set B is

प्रश्न - f:RB, यदि f(x) = sinx तथा दिया गया f(x) एक आच्छादक फलन है, तब समुच्चय B है
