Finding X in Polynomial

Complete the sentence (2 right answers): the multiplicity of an x-intercept...

• Determines exactly what happens near the x-int on the graph

• Helps with the calculation of the x-int

• May determine the sign of the leading coefficient

• Suggests two possibilities for the behavior of the graph near the x-int

• 0, 6, -5

• 6, -5

• 0, -6, 5

• 1, -6, 5
