Vertex: The vertex of the quadratic function y = (x + 4)(x - 2) can be found by converting it to vertex form or using the formula for the vertex of a parabola in standard form. The vertex is at (-1, -9).x-intercepts: The x-intercepts are the solutions to (x + 4)(x - 2) = 0, which are x = -4 and x = 2. Therefore, the x-intercepts are (-4, 0) and (2, 0).
