A) equal to\[\alpha \]
B) greater than or equal to\[\alpha \]
C) smaller than\[\alpha \]
D) greater than \[\alpha \]
Correct Answer: C
Solution :
Let\[f(x)={{a}_{n}}\,{{x}^{n}}+{{a}_{n-1}}\,{{x}^{n-1}}+...+{{a}_{1}}\,x=0,\] \[{{a}_{1}}\ne 0\] It have rootsand So, definitely its derivative is zero between 0 and. According to the Rolle's theorem, has a positive root smaller than.You need to login to perform this action.
