Answer
$\mathrm{x} = 5$ has multiplicity 1 (odd)
The graph crosses the x-axis.
$\mathrm{x} = \text{–}4$ has multiplicity 2 (even)
The graph touches the x-axis and turns around.
Work Step by Step
Multiplicity and x-lntercepts
If r is a zero of a polynomial f(x), then $(x-r)^{k}$ is a factor in the full factorization of f.
The exponent indicates the multiplicity of r.
If $r$ is a zero of even multiplicity, then the graph touches the x-axis and turns around at $r$.
If $r$ is a zero of odd multiplicity, then the graph crosses the x-axis at $r$.
