 5. Identify a, b, and c. a =-1, b= 5, c=

5. Identify a, b, and c. a =-1, b= 5, c= -3 Find the axis of symmetry and sketch the line. x 2a 5 x - 2(-1) LO | Q x The axis of symmetry is x = LO IN The x-coordinate of the vertex is also LOIN Find the y-coordinate of the vertex. f(x) -- 13 The vertex is 5 13) S ec= -3, the y-intercept is (o, - 3). Reflect across the axis of symmetry to get (5, -3). confirms the graph opens downward. Domain: All real numbers. There is no restriction on the value of x. Range: y s 13 , since the minimum value of the function is 13
