5. Continuity and Differentiation

यदि मध्यमान प्रमेय से, $f'({x_1}) = \frac{{f(b) - f(a)}}{{b - a}}$, तो

A

$a < {x_1} \le b$

B

$a \le {x_1} < b$

C

$a < {x_1} < b$

D

$a \le {x_1} \le b$

Solution

(c) $f (x)$  के लिए अंतराल  $[a, b] $ में मध्यमान प्रमेय से,

$\frac{{f(b) – f(a)}}{{b – a}} = f'(c)$, जहाँ $a < c < b$

$\therefore a < {x_1} < b$.
