Parameters: a=−1/2, h=−4, k=0. Endpoint: (−4,0). Domain: [−4,∞). Range: (−∞,0]. Anchors: (−3,−1/2), (0,−1), (5,−3/2).

Parameters: a=2, h=−4, k=0. Endpoint: (−4,0). Domain: [−4,∞). Range: [0,∞). Anchors: (−3,2), (0,4), (5,6).

Parameters: a=−2, h=4, k=0. Endpoint: (4,0). Domain: [4,∞). Range: (−∞,0]. Anchors: (5,−2), (8,−4), (13,−6).

Parameters: a=−2, h=−4, k=0. Endpoint: (−4,0). Domain: [−4,∞). Range: (−∞,0]. Anchors: (−3,−2), (0,−4), (5,−6).
