Only C) The function is increasing on the interval (-2,∞)

Explanation:

`2√(x+3)-3` is undefined on the interval (-∞,-2),(-∞,0) .So we can eliminate a) and b).As for the second option, Although interesting, It's incorrect. On the interval (-2,∞) , it's increasing not decreasing. Hence, Option C is correct!
