Give the coordinates of the vertex and graph the equation in a window that includes the vertex. 1) y = (x- 17) 2 + 4 x y x y A) Vertex: (4,- 17) x-12-8-4 4 8 12 y 20 16 12 8 4-4-8-12-16-20 x-12-8-4 4 8 12 y 20 16 12 8 4-4-8-12-16-20 B) Vertex: (- 17, 4) x-20-16-12-8-4 y 20 16 12 8 4 x-20-16-12-8-4 y 20 16 12 8 4 C) Vertex: (17, 4) x 4 8 12 16 20 y 20 16 12 8 4 x 4 8 12 16 20 y 20 16 12 8 4 D) Vertex: (4, 17) x 4 8 12 16 20 y 32 28 24 20 16 12 8 4 x 4 8 12 16 20 y 32 28 24 20 16 12 8 4 Determine if the vertex of the graph is a maximum point or a minimum point. 2) y = - (x + 4) 2 A) Maximum B) Minimum 1 Solve the problem. 3) An object is thrown upward with an initial velocity of 10 ft per sec. Its height is given by h(t) = - 10t 2 + 60t at time t seconds. After how many seconds does it hit the ground?...
