The function h(x) = –2x2 + 8x written in vertex form is h(x) = –2(x – 2)2 + 8. The function h(x) is shown on the graph along with the parent function, f(x) = x2. Which statement is true concerning the vertex and axis of symmetry of h(x)? The vertex is at (0, 0) and the axis of symmetry is x = 2. The vertex is at (0, 0) and the axis of symmetry is y= 2. The vertex is at (2, 8) and the axis of symmetry is x = 2. The vertex is at (2, 2) and the axis of symmetry is y = 2.
