A) \[[-5,-4]\cup [1,2]\]
B) \[[-13,-2]\cup [3/5,5]\]
C) \[[4,1]\cup [2,7]\]
D) \[[-3,2]\]
Correct Answer: A
Solution :
\[1\le {{\log }_{2}}({{x}^{2}}+3x-2)\le 3\] \[\Rightarrow \]\[2\le ({{x}^{2}}+3x-2)\le 8\] \[\Rightarrow \]\[-5\le x\le -4\]or \[1\le x\le 2\]You need to login to perform this action.
