What is the axis of symmetry and vertex for the graph #p(x)=(x+5)^2-3#?
The vertex is at
This quadratic function is written in "vertex form", or
The axis of symmetry is just an imaginary line that goes through the vertex of a parabola where you would fold if you folded the parabola in half, with one side on top of the other.
Since that would be a vertical line through
