You can put this solution on YOUR website! Find the vertex, the line of symmetry, the maximum or minimum value of f(x. Graph the function:
----
Comment: Your equation is in the form y = a(x-h)^2+k
where (h,k) is the vertex.
----------------------------
f(x)=1/2(x+9)^2+5
---
Vertex: (-9,5)
---
Line of symmetry is the vertical line thru the vertex: x = -9
---
Since (1/2) is greater than zero, the parabola opens up, so it
has a minimum y-value at the vertex:
minimum value = 5
