can you show me how to do this Answer & explanation by AI Answer and how to graph f(x) = (x + 1) 1 Shape: Parabola opening downward (because of the leading negative). Vertex: shift left 1 and down 1 from y = x vertex at (1, 1). Axis of symmetry: x = 1. y-intercept: f(0) = (1) 1 = 2 point (0, 2). x-intercepts: none, since (x + 1) 1 = 0 (x + 1) = 1 (no real solution). Range: (, 1]; Domain: all real numbers. Points to plot: Vertex: (1, 1) Symmetric points: (0, 2) and (2, 2) More points: (1, 5) and (3, 5) Sketch a downward-opening parabola through these points with axis of symmetry x = 1
