What is the formula to find the axis of symmetry? The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a . What is the axis of symmetry ...
I believe x=-b/2a is the axis of symmetry, not y=-b/2a, as you explain. Report 01/10/14 Steve S. One way to remember this is with the Quadratic Formula: x = (-b±√(b^2-4ac))/2/a = -b/2/a ±√(b^2-4ac))/2/a The roots are equal distances from the value x ...

I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observat...
