For the quadratic function f left parenthesis x right parenthesis equals negative x squared minus 4 xf(x)=x24x, answer parts (a) through (c). Question content area bottom left Part 1 (a) Graph the quadratic function by determining whether its graph opens up or down and by finding its vertex, axis of symmetry, y-intercept, and x-intercepts, if any. Does the graph of f open up or down? down Your answer is correct. up Part 2 What are the coordinates of the vertex? The vertex of the parabola is left parenthesis negative 2,4 right parenthesis(2,4). (Type an ordered pair. Use integers or fractions for any numbers in the expression.) Part 3 What is the equation of the axis of symmetry? The axis of symmetry is x equals negative 2x=2. (Type an equation.) Part 4 What is/are the x-intercept(s)? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The x-intercept(s) is/are 0,negative 40,4. (Type an integer or a decimal. Use a comma to separate answers as needed.) Your answer is correct.B. There are no x- intercepts. Part 5 What is the y-intercept? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The y-intercept is 00. (Type an integer or a decimal.) Your answer is correct.B. There is no y-intercept. Part 6 Use the graphing tool to graph the function. Part 7 (b) Determine the domain and the range of the function. The domain of f is left parenthesis negative infinity,infinity right parenthesis(,). (Type your answer in interval notation.) Part 8 T
