e Valsky Ch6.7-8 plus review Question 24, 5.1.87-GC HW Score: 90.6%, 29.9 of 33 points Part 10 of 12 Points: 0.85 of 1 Save K Analyze the polynomial function f(x) = (x + 5)(x - 4)(x + 8). Complete parts (a) through (h)- The x-intercept(s) is/are -5,4, - 8. (Type an integer or a simplified fraction. Use a comma to separate answers as needed. Type each answer only once.) The y-intercept is - 160 (Type an integer or a simplified fraction.) (c) Determine the zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the x-axis at each x-intercept. The zero(s) of f is/are - 8, - 5,4 . (Use a comma to separate answers as needed. Type each answer only once.) The smallest zero is a zero of multiplicity 1 , so the graph of f crosses the x-axis at x = - 8 . The middle zero is a zero of multiplicity 1 , so the graph of f crosses the x-axis at x = - 5 . The largest zero is a zero of multiplicity 1 , so the graph of f crosses the x-axis at x= 4. (d) Use a graphing utility to graph the function. Use the window [ - 15,15,3] by [- 350,350,35]. Choose the correct graph below. O A B. YC. DD. (e) Approximate the turning points of the graph. Round the coordinates to two decimal places as needed. Select all that apply DA. (4,0) DB. (-8,0) LY C. (-6.61,23.74) LD. (0.61, - 163.74) DE. (-5,0) (f) Use the above information to draw a complete graph of the function by hand. Choose the correct graph below. OA. OB. &C. OD (g) Find the domain and the range of the function. The domain of the function is (- 0o,00) (Type your answer in interval notation.) The range of the function is (Type your answer in interval notation.)
