the vertex of the graph is (-3, 4) and is opening downwards.... now it should be easy to choose the correct answer....

anonymous · Answer

from the hint above can you at least eliminate two of the possibilities?

anonymous · Answer

use the fact that the x-coordinate of the vertex is -b/(2a)... now you can match up the equation that gives you the -3 as the x-coordinate of the vertex.

can you try?
