Polynomial 9.1-9.4 Quiz

Select the interval(s) of increasing.

•  $\left(-\infty,-1\right)$  

•  $\left(-1,2\right)$  

•  $\left(2,\infty\right)$  

•  $\left(-\infty,\infty\right)$  

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

• y = x(x - 3)(x - 2)
• y = x(x - 3)² (x+2)
• y = x(x + 3)² (x - 2)
• y = -x(x + 3)² (x - 2)

For each function, determine the real zeros and state the multiplicity of any repeated zeros.

• {0 mult. 3, 5, 2}

• {−2 mult. 3, 3, 1}

• {0 mult. 3, 3, 2}

• {2 mult. 3, 3, 3}

Which of the following correctly identifies the End Behavior?

• 
• 
• 
• 

Which root has a multiplicity of 2?

• -1

• 2

• 4

• -4

What are the increasing intervals?

• (- ∞, -1) & (-1, 0) & (0, 1) & (1, ∞)

• (3, 4) & (3, 8)

• (- ∞, -1) & (1, ∞)

• (-1, 0) & (1, ∞)

What is the y-intercept?

f(x) = -x⁴ + x³ + 5x² + x + 6

• (6, 0)

• (-6, 0)

• (0, -6)

• (0, 6)

Match the graph to the function. (Hint: Remember the last question about the y-intercept.)

• f(x) = -x⁴-x³+5x²-6

• f(x) = x⁴+3x²-3x+1

• f(x) = -x³+2x²-x-6

• f(x) = x⁴+x³+5x²-6

Match the graph to the function

• f(x) = -2x⁶+9x²
• f(x) = x⁶-7x⁴+12x²-x-2
• f(x) = x⁶-3x³+x+2
• f(x) = -x⁶+5x⁴+3x-2
