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 is undefined on the interval <em>(</em><em>-</em><em>∞</em><em>,</em><em>-</em><em>2</em><em>)</em><em>,</em><em>(</em><em>-</em><em>∞</em><em>,</em><em>0</em><em>)</em><em> </em>.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!
