Following a polynomial, find
a. the zero's and the multiplicity of each
b. where the graph crosses or touches the xaxis
c. the number of turning points
d. the end behavior
f(x)=(x+3)(x5)(x+5)

Steve,
the zeros are shown above, each of multiplicity 1
the zeros are where the graph crosses the axis, since there are no multiple roots
since the graph crosses the axis 3 times, there are 2 turning points
graph rises up from lower left, turns twice, and exits to upper right
