Find the vertex, the line of symmetry, and the maximum or minimum value of f(x). Graph the function.
f(x) = 1/5(x+8)^2+2
1) The vertex is "ordered pair" ??
2) The line of symmetry is x = ??
3) What is the maximum/minimum value of f(x) ??
4) Is the value, f(-8) = 2 a minimum or maximum ?? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Don't be lost, study the "vertex form".
.
.
.
The equation is already in vertex form, where (h,k) is the vertex.
1) Comparing, (h,k)=(-8,2)
.
.
2) The vertex lies on the axis of symmetry,
.
.
3) Since and , then the parabola opens upwards and the value at the vertex () is a minimum.
.
.
4) From 3), it's a minimum.
