A) [1, 4]
B) [1, 0]
C) [0, 5]
D) [5, 0]
Correct Answer: A
Solution :
The function\[f(x)=\sqrt{{{\log }_{10}}\left( \frac{5x-{{x}^{2}}}{4} \right)}\]exists for \[\frac{5x-{{x}^{2}}}{4}\ge 1\]\[\Rightarrow \]\[5x-{{x}^{2}}-4\ge 0\]\[\Rightarrow \]\[x\in [1,4]\]You need to login to perform this action.
