7. (2 Points) For the polynomial function f(x) = -x* + 4x? a. Use the Leading Coefficient Test to determine the graphâ€™s end behavior. b. Find the x-intercepts. State whether the graph crosses the x-axis, or touches the x-axis and tums around, at each intercept. c. Find the y-intercept. d. Determine whether the graph has y-axis symmetry, origin symmetry, or neither. e. Ifnecessary, find a few additional points and graph the function. Use the maximum number of turing points to check whether it is drawn correctly. Use the coordinate template below to draw the graph of f(x).
