If \( r \) is a zero of even multiplicity, then the graph touches the \( x \)-axis and \( \text{turns around} \) at \( r \). If \( r \) is a zero of odd multiplicity, then the graph \( \text{crosses} \) the \( x \)-axis at \( r \).
Thus, the filled-in statements are:
- "If \( r \) is a zero of even multiplicity, then the graph touches the \( x \)-axis and \(\boxed{\text{turns around}}\) at \( r \)."
- "If \( r \) is a zero of odd multiplicity, then the graph \(\boxed{\text{crosses}}\) the \( x \)-axis at \( r \)."
