Question

Ay U 3- Use the vertex and intercepts to sketch the graph of the quadratic function Give the equation for the parabola's axis of symmetry. Use the parabola to identify the function's domain and range, fix)=x2-x-2 Use the graphing tool to graph the equation. Use the vertex and one of the intercepts to graph the equation. Click to enlarge graph 2 1 2 The axis of symmetry is (Type an equation) Identify the function's domain The domain is (Type the answer in interval notation) Identify the function's range The range is (Type the answer in interval notation) -

Answer 1

C = -2 y = x²-x-2 for a intercept, y=0 » 0 = x2-x-2 80 point onx-axis (x+1)(2-2)=0 (0)412,0) x = 4,2 for y intercept, x=0,=y=0-0-2 80 point on y-axis y=-2 (0,-2) Bre comparing eq" o with y=an²+bxtc, we get a=1, b=-1, vertex = (-1 Lai I a) = (- 6 11242c)) qa = (1 -(1-4X1X(-2)) UXI -() vertex = (0.5, - 2-25) $0 axis of symmetry is (from graph) 1x=0.5 Answer / 2X1 domain 1-00,00) [-2.25, 0) Auswer Range Scanned with CS CamScanner
