A) \[[2,3)\]
B) \[(2+{{2}^{3/4}},4)\]
C) \[[3,2+{{2}^{3/4}}]\]
D) \[[4,6]\]
Correct Answer: D
Solution :
put\[b=\frac{2+c}{2}\] in determinant of A \[|A|=\frac{{{c}^{3}}-6{{c}^{2}}+12c-8}{4}\in [2,16]\] \[\Rightarrow \]\[{{(c-2)}^{3}}\in [8,64]\]\[\Rightarrow \]\[c\in [4,6]\]You need to login to perform this action.
