What is the axis of symmetry and vertex for the graph #x-4 = 1/4 (y+1)^2#?
Axis of symmetry is
This is a quadratic in y. So instead of form
Consequently it is still of general shape
Write the equation as:
This equation format is in what is called 'Vertex Form'. With a slight adjustment you can read off the vertex coordinates directly from it
This is taken directly from the equation without change
