Question

I neeed help finding the vertex and axis of symmetry.
If you maybe show me how to do one I could catch on!
1. F(x)=(1/2)(x+2)^2-(1/4)

Answer 1

ill help you in a second, if no one else does. let me finish helping someone.

Answer 2

ok thanks!~~~

Answer 3

First, before I tell you how to find them, do you know what they are?

Answer 4

Well I know the vertex.. not the axis of symmetry

Answer 5

The axis of symetry is the line that if you draw it on the graph of the function, the side on one side of the line (not necessarily vertical) will be the mirror image of the other.

Answer 6

Oh okay...

Answer 7

Since the vertex is just the spot where the parabola changes direction (if I remember properly) you just pick the smallest y coordinate if the parabola is positive and the largest y coordinate if the parabola is negative.

Answer 8

i dont get that
