A) Strictly decreasing
B) Strictly increasing
C) Decreasing in (2, 3) only
D) Neither increasing nor decreasing
Correct Answer: B
Solution :
\[f(x)=3x+\frac{2}{x}\] Þ \[{f}'(x)=3-\frac{2}{{{x}^{2}}}\] Clearly \[{f}'(x)>0\] on the interval (1, 3) \ \[f(x)\] is strictly increasing.You need to login to perform this action.
