You can put this solution on YOUR website!
f(x)= 1/4(x+9)^2+1
------------
It's in standard form, so the LOS is x = -9
The vertex is (-9,1), taken from the standard form.
The minimum is the vertex.

==========================================
f(x)= 1/4(x+9)^2+1
Since this parabola opens upward, the vertex will be a minimum value
The function has a minimum at x = -9
f(-9) = 1
So the vertex is (-9,1)
The line of symmetry runs parallel to the y-axis and goes through the vertex (-9,1).
Therefore the line of symmetry is x = -9
The graph is below:

The minimum value is the vertex (-9,1)
The maximum value is infinity
