A) 1
B) \[\frac{1}{3}\]
C) -1
D) 2
Correct Answer: D
Solution :
\[f'(x)=6(x-1)(x-a)\] If \[a<1,\]then\[{{x}_{1}}=a\]is point of maxima and\[{{x}_{2}}=1\]is point of minima. Hence,\[a=\frac{1}{2}\] If \[a>1,\]then\[{{x}_{1}}=1\]is point of maxima and \[{{x}_{2}}=a\]is point of minima. Hence, a =2You need to login to perform this action.
