[ r is called a (real) zero of f , or root of f when ) ( = r f ] ) 4 ( ) 2 ( ) ( 2 + ! = x x x f (a) Find the xintercepts and the yintercepts of the above polynomial function f . (b) Determine whether the graph touches or crosses the xaxis at each xintercept. (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 xintercept(s) to find the intervals on which the graph of f is above and below the xaxis. (f) Plot the points and connect them with a smooth and continuous curve....
