The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
For 3. he answer is a
for 4 the answer is two
D, because the sum is no more than 28 so it could be equal or less than.
A point , (x,y) is reflected across the y axis. the resulting point is (-x,y)
so
if (5.75,0) is the reflected point, then (-5.75,0) is the original
the distance is the double the absolute value of the x value (basically a horizontal line beteen the 2 points)
so
2|-5.75|=2(5.75)=11.5
distance is 11.5 units
I think B is the closest answer
