What is the axis of symmetry for f(x) = 2x2- 4x + 5? Axis of Symmetry of a Parabola: In mathematics, a parabola is a graph of a quadratic function,f(x) =ax2+bx+c, that has the shape of a U or an upside down U. The axis of symmetry of a parabola is the vertical lin...
Axis of Symmetry:This is a vertical line that runs through the middle of a quadratic function. The graph on the left side of the axis of symmetry is a mirror image of the graph on the right side of the axis of symmetry. The equation for the axis of symmetry is: ...

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 ...
A reference direction for angular coordinates used in describing the directional characteristics of a transducer; it is usually an axis of structural symmetry or the direction of maximum response. (mathematics) One of a set of perpendicular axes such that a quadratic function can be written as a ...
