What does "multiplicity" mean on graphs?

• The y-intercept is at (0,0).

• The graph has more than one maximum.

• The graph goes to positive infinity.

• The x-intercepts count more than once.

Based on the graph, list the roots as points.

• (-3, 0) and (-2, 0)

• (-1, 0) and (2, 0)

• (0, -1) and (0, 2)

• (5, 0)

Based on the graph, write the equation in factored form.

*HINT: Pay attention to multiplicity/bounces*
