Analyze the polynomial function f(x) = 5x (x² - 9) (x + 4) using parts (a) through (e). (a) Determine the end behavior of the graph of the function. The graph off behaves like y = 5x^4 for large values of [x]. (b) Find the x- and y-intercepts of the graph of the function. The x-intercept(s) is/are. (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed. Type each answer only once.)
