Review Graphs of Polynomials

Which of the following IS NOT A FACTOR of the polynomial graphed here?

• x

• ( x - 1 )

• ( x + 1 )

• ( x + 2 )

Find the vertex of y = - x² + 6x - 8.

• ( 3 , - 35 )

• ( - 3 , 2 )

• ( - 3 , - 35 )

• ( 3 , 1 )

Name the axis of symmetry:

y = 5x² - 25x + 1

• y = 5/2

• x = 5/2

• x = - 5/2

• y = - 5/2

What is the range of this function:

f(x) = - x² + 4

• [ 4 , ∞ )

• ( - ∞ , 4 ]

• [ - 4 , ∞ )

• ( - ∞ , - 4 ]

Remember to look at your roots, multiplicity, and end behavior!! Use your notes!

• y = ^_(x + 2)(x - 1)²

• y = -(x - 2)(x + 1)²

• y = (x - 2)(x + 1)²

• y = -x³

• A.
• B.
• C.
• D.

In the above graph, which root has a multiplicity of 2?

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• -1

• -3

• -120

• 4

Select the two descriptions that best describe the polynomial FUNction's graph.

• Even degree

• Odd degree

• Negative leading coefficient

Match the equation to the graph.
Remember to look at your roots, multiplicity, and end behavior!!
Use your notes!

• y=-(x+1)(x-2)(x-4)

• y=(x+1)²(x-3)(x-1)³

• y = 3x³ – 2x + 1

• y=(x+1)³(x-3)(x-1)²

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