Solution Steps

To fill in the blanks, we need to understand the behavior of polynomial graphs at their zeros based on the multiplicity of the zeros. For a zero of even multiplicity, the graph touches the x-axis and turns around at that point. For a zero of odd multiplicity, the graph crosses the x-axis at that point.

Step 1: Understanding Even Multiplicity

For a zero \( r \) of even multiplicity, the graph of the polynomial touches the \( x \)-axis at \( r \) and turns around. This means that the graph does not cross the \( x \)-axis but instead bounces off it.

Step 2: Understanding Odd Multiplicity

For a zero \( r \) of odd multiplicity, the graph of the polynomial crosses the \( x \)-axis at \( r \). This indicates that the graph changes direction as it passes through the \( x \)-axis.

Final Answer

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 \( r \)."
