MCQ

Rolle's theorem is true for the function $f(x) = {x^2} - 4 $ in the interval

A
$[-2, 0]$
✓
$[-2, 2]$
C
$\left[ {0,\,{1 \over 2}} \right]$
D
$[0,\,\,2]$

✓

Answer

Correct option: B.

$[-2, 2]$

b
(b) If Rolle's theorem is true for any function $f(x)$ in $[a,\,b].$

Then $f(a) = f(b),$ therefore $ [-2,2].$
