1. Given the polynomial

f(x) = x2(x - 7)2(x - 18)(x + 4)3

1. Find the zeros of the expression, and their multiplicities
2. At each zero, determine whether the graph crosses the x-axis, or merely touches the x-axis and
3. bounces off
4. Find the maximum number of turning points
5. Find the power function, and use it to characterize the function's end behavior
