(b) Determine whether the graph touches or crosses the x-axis at each x-intercept. (c) Check end behavior: Find the power function that the graph of f resembles for large values of x . (d) Determine the maximum number of turning points of the graph of f. (e) Use the x-intercept(s) to find the intervals on which the graph of f is above and below the x-axis.
