Answer:
The correct option is 2.
Explanation:
From the given graphs in is clear that


we need to find the interval for which (f-g)(x) is negative.

Substitute the values of both functions.



The value of (f-g)(x) is negative mean the value (f-g)(x) is less than 0.

Add 3 on both sides.

Divide both sides by 1.5.


For all x<2, the value (f-g)(x) is negative. It means for the interval (-∞,2) the value (f-g)(x) is negative.
Therefore the correct option is 2.
