A) \[0\]
B) \[1\]
C) \[2\]
D) More than 2
Correct Answer: B
Solution :
[b] According to given information, a is the point of inflection of \[y=f(x)\]. \[\therefore \,\,\,\,\,\,f''(\alpha )=0\Rightarrow \alpha =0\] \[f'(0)=5\] and \[\frac{f(b)-f(a)}{b-a}={{b}^{2}}+ab+{{a}^{2}}+5\] \[=\left( b+\frac{a}{2} \right)+\frac{3{{a}^{2}}}{4}+5>5\,\,\forall a\ne b\in R\]You need to login to perform this action.
