Question 633082: I am to find the vertex, the line of symmetry, as well as the maximum or minumum value of f(x). Graph the function.
I am sorry but I just am not comprehending how to do this. I have looked at problems in the book, on here and as sad as it sounds I just am comprehending it. Please help me
f(x)= -(x+1)^2-9 Answer by reviewermath(507) (Show Source):
You can put this solution on YOUR website! The vertex of the quadratic function is (h,k).
The line of symmetry is and the maximum or minimum value is k.
Therefore, in , the vertex is (-1,-9).
The line of symmetry is and the maximum value is .
The graph has a maximum value because a < 0.
here's the graph:
