Question 632782: Can someone please help me wih this problem because I am so confused. Ineed to now how to find the vertex, the line of symmetry, and the maximum or minimum value of f(x). Graph the function also. Please help me and thanks so much in advance.
f(x)=(1/4)(x+8)^2+8

You can put this solution on YOUR website!
The vertex of the quadratic function y+=+a%28x-h%29%5E2+%2B+k+is (h,k).
The line of symmetry is x+=+h and the maximum or minimum value is k.
Therefore, in f%28x%29+=+%281%2F4%29%28x%2B8%29%5E2%2B8, the vertex is (-8,8).
The line of symmetry is highlight%28x+=+-8%29 and the minimum value is highlight%288%29.
The graph has a minimum value because a > 0.
here's the graph:
