For the quadratic function f left parenthesis x right parenthesis equals 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? up Your answer is correct. down Part 2 What are the coordinates of the vertex? The vertex of the parabola is left parenthesis 2,negative 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 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 0,40,4. (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 The range of f is left bracket n
