Determine the zeros of the function and their multiplicity :
\Use this information to determine whether the graph crosses or touches the
-axis at each
-intercept.
The zeros of the function are
and
.
The zero
is a zero of multiplicity
, so the graph of
crosses the
-axis at
.
The zero
is a zero of multiplicity
, so the graph of
crosses the
-axis at
.
The zero
is a zero of multiplicity
, so the graph of
crosses the
-axis at
.
