Please help with last part, at which zero(s) does the graph of the function cross the x-axis?

Use the given function to complete parts a) through e) below. f(x) = -3(x - 1)- (x2 -9) a) Use the Leading Coefficient Test to determine the graph's end behavior. The graph of f(x) falls left and falls right. The graph of f(x) falls left and rises right. O The graph of f(x) rises left and falls right. The graph of f(x) rises left and rises right. b) Find the x-intercepts. The X-intercept(s) is/are 1,3, -3 (Type an integer or a decimal. Use a comma to separate answers as needed.) At which zero(s) does the graph of the function cross the x-axis? Select the correct choice below and, if necessary, fill in the answer box to complete your choice A. The graph crosses the x-axis at the zero(s) (Type an integer or a decimal. Use a comma to separate answers as needed.) O B. There are no zeros at which the graph crosses the x-axis
