Answer 1

Answer:

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

Step-by-step explanation:

As we know square root function is only defined for all the value of x greater than or equal to 0 . That being said, the function $2\sqrt{x+3}-3$ 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!
