Increasing and Decreasing of Polynomial Graphs

When determining where a graph is increasing/ decreasing use...

• x-values

• y-values

The blue dot on this graph represents a(n)...

• Absolute Maximum

• Absolute Minimum

• Local Maximum

• Local Minimum

identify zeros

• (-1,0)

• (0,-1)

• (-0.333,1.333)

• (0.333,0)

How many zeros can this function have?

• only 1

• must have 2

• 1-2

• 0-2

Does (-1,0) have multiplicity of 1 or 2?

• 1

• 2

• 0

Does (1,0) have multiplicity of 1 or 2?

• 1

• 2

• 0

• (-2.55, 0), (2.55, 0)
• (-3, 0), (-2, 0), (2, 0), (3, 0)
• (0, 36)
• (0, -3), (0, -2), (0, 2), (0, 3)

• (1, 4)
• (0, 2)
• (-1, 0)
• (2, 0)

• (0, 4)
• (2, 0)
• (0, 2)
• (-1, 0)

• y =  ^_(x + 2)(x - 1)²
• y = -(x - 2)(x + 1)²
• y = (x - 2)(x + 1)²
• y = -x³
