Find the axis of symmetry and the vertex of the graph of f(x) = 2x^2 - 4x.

The axis of symmetry is x= , and the vertex is (__,__).

Triangle xyz with vertices x(0, 0), y(0, –2), and z(–2, –2) is rotated to create the image triangle x'(0, 0), y'(2, 0), and z'(2, –2). which rules could describe the rotation? check all that apply. r0, 90° r0, 180° r0, 270° (x, y) → (–y, x) (x, y) → (y, –x)
