For the quadratic function f(x) = x² + 4x - 8, find the vertex, the axis of symmetry, and the x-intercept(s). Express the vertex as a coordinate pair. If there is more than one intercept, enter as a comma separated list of points. ▪ vertex: (-2,-12) help (points) ■ axis of symmetry: x = -2 help (numbers) ▪ x-intercept(s): (−2+2√3, 0),(−2−2√3, 0) help (points)
