Question 318797: Find the vertex, line of symmetry, maximum/minimum and if the graph opens up or down of: f(x)=1/4(x+1)^2+9 Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! The equation is in vertex form, , where (h,k) is the vertex.
Comparing,
(h,k)=(,)
The vertex lies on the axis of symmetry,
The coefficient of the term is positive, so the parabola opens upwards and the minimum for the parabola occurs at the vertex.
