Graphing Polynomial Function

• The increasing interval of the polynomial function.

• The domain of the function.

• The decreasing interval of the polynomial function.

• The range of the function.

Write an interval to describe the decreasing part of the polynomial function.

• (-3,-5)

• (-5,-3)

Describe the end behavior of the polynomial function?

• The answer is not here.

• The leading coefficient is positive.

• The highest degree is even.

• The leading coefficient is negative.

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

Which equation MOST LIKELY matches the graph?

• y = x⁴ - x³ + 3x² + 2

• y = -x⁴ + x³ + 5x + 2

• y = x³ - 2x² + 1x + 3

• y = -x³ - 2x² + 1x + 3

• -1

• -3

• -120

• 4

If a zero of a polynomial function has multiplicity 3 that means:

• The x intercept is at (4, 0)

• The graph will "bounce back" at that zero

• The graph will "pass through" at that zero

• Zeros cannot have multiplicity of 4
