Using a graph tool
see the attached figure
The graph is increasing in the interval (-0.15,2) and the interval (3.4, ∞)
The graph is decreasing in the interval (-∞, -0.15) and the interval (2,3.4)
therefore
the interval (1,2) is included in the interval (-0.15,2)
<u>the answer is the option</u>
C. X:1 to x:2
