Question 101712: I am lost on what to do with is the given data. The question is;
Determine the vertex of the parabla: y=(x+2)^2
What is the axis of symmetry?
I know the axis of symmetry is h but how do I find the h?
Thank you for your time
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Determine the vertex of the parabla: y=(x+2)^2
Vertex form is y-k = (x-h)^2
The vertex is at (h,k)
Your Problem:
y-0 = (x-(-2))^2
Vertex is at (-2,0)
--------------------
What is the axis of symmetry?
Axis of symmetry is a vertical line thru the vertex.
Axis of symmetry equation: x=-2
