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 $[a,\,b].$
(b) If Rolle's theorem is true for any function $f(x)$ in $[a,\,b].$
Then $f(a) = f(b),$ therefore $ [-2,2].$
