axis of symmetry

When a structure is rotated through an angle of 2 p /n about an imaginary axis and then reflected across a plane perpendicular to the axis, an identical structure result..

What is the axis of symmetry of a parabola? => y -axis or its focal axis or its directrix or x -axis..

Find the equation of the parabola with focus at (- 7, 0) , x - axis as the axis of symmetry and vertex at origin. => y 2 = - 7 x or y 2 = - 28 x or y 2 = 28 x or x 2 = 28 y..

Find the equation of a function whose graph is a parabola with an axis of symmetry of x = - 9 . => y = a ( x + 9) 2 + k or y = a ( x - 9) 2 - k or y = a ( x - 9) 2 + k or y = a ( x + 9) 2 - k..

Justin threw a stone over a 6-ft wall . The stone just clears the wall (without much extra space) and hits the ground 8-ft from the wall. What would be the equation that approximates the path of the stone, if the wall is used as the axis of symmetry and the origin is the point a..

Draw the graph of the given equation. Mark the maximum or minimum point and the axis of symmetry: y = - 7 x 2 - 4 => Graph 4 or Graph 1 or Graph 3 or Graph 2..

What is the axis of symmetry of the graph of y = - x 2 + 9? => x = 1 or x = 1 2 or x = 0 or x = -1..

What is the axis of symmetry of the graph of y = x 2 /4? => x = 1 or x = 0 or x = 4 or x = 1 4..

What is the axis of symmetry of the graph of y = - x 2 ? => x = - 1 or x = 1 2 or x = 1 or x = 0..

Determine if the parabola opens up or down. Then, find the equation of the axis of symmetry and the coordinates of the vertex for the function y = 3 x 2 . => opens down; x = 0; (0, 0) or opens up; x = 3; (0, 0) or opens up; x = 0; (0, 0) or opens down; x = 3; (0, 0)..
