Answer: C) All real values of x such that 
In other words, x must be 0 or smaller.
===================================================
Explanation:
The reason why is because we must make the stuff under the square root to never be negative. We must make -2x be 0 or larger.
So,

As an example, if x = -2, then -2x = -2(-2) = 4 is positive. Applying the square root to a positive number is valid.
But if x = 5, then -2x = -2*5 = -10 is under the square root, which is not allowed.
Answer:
vertex (-3,5) and another pt (-2,4)
Step-by-step explanation:
It is in vertex form so the vertex is (-3,5)...
Now just plug in a value for x say like -2...
f(-2)=-(-2+3)^2+5
f(-2)=-(1)^2+5
f(-2)=-1+5
f(-2)=4
So another point is (-2,4)
