Answer:
Formula Of Vertex and Line of symmetry
Step-by-step explanation:
The axis of symmetry always passes through the vertex of the parabola . 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
Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex"
Answer:
2011,2012,2013,2014,2015
Step-by-step explanation:
Check the picture below.
you simply come "clockwise" to get the negative angle.
and to get the positive angle, simply go around 2π and then add π/7 to it.
