Use the vertex and intercepts to sketch the graph of the quadratic function. Give the equation of the parabola's axis of symmetry. Use the graph to determine the function's domain and range. f ( x ) = x2 +6x + 5 Use the graphing tool to graph the equation. Use the vertex and one of the intercepts when drawing the graph of x 10 8 5 4 Click to enlarge graph The axis of symmetry is (Type an equation.) The domain of f is (Type your answer in interval notation.) The range of f is (Type your answer in interval notation.)
