A) \[f\] has two maxima and one minima
B) \[f\] has only one point of inflection
C) \[f\] increases in the intervals \[(0,1)\cup (2,\infty )\] and decreases in \[(-\infty ,\,0)\cup (1,2)\]
D) \[f\] decreases in the interval \[(0,1)\,\cup \,(2,\infty )\] and increases in the interval \[(-\infty ,0)\,\cup \,(1,2)\].
Correct Answer: C
Solution :
\[f'(x)=2x(x-2)(2x-2)=4x(x-1)(x-2)\] Now verifyYou need to login to perform this action.
