Informally speaking, an axis of symmetry can be thought of as a mirror and, in this context, the symmetry would be the object in front of the mirror along with its reflection.View Video Only Save Timeline Video Quiz Course 771K views What is a Parabola? Consider a line and a ...
Axis of Symmetry of a ParabolaThe line passing through the focus and vertex of a parabola. The axis of symmetry is perpendicular to the directrix.Example: This is a graph of the parabola with all its major features labeled: axis of symmetry, focus, vertex, and directrix....
Find the axis of symmetry for y=x2+4x−7. Parabola; Axis of Symmetry:The axis of symmetry in the case of a parabola is defined as that line that passes through the vertex of the parabola and divides it into two equal halves. Here we will use the standard form of the parabola ...
The parabola represents the graph of a quadratic function. The axis of symmetry is the value where the graph is divided into two equal parts. We can obtain the axis of symmetry of a quadratic function by finding the x-coordinate of the vertex, which uses the following formula:...
A parabola with its vertex at (20,8) and its axis of symmetry parallel to the y-axis passes through point (25,28) . Write an equation of the parabola. Then find the value of y when x=40 .
