Match the equation to the graph.

• y=-(x+1)(x-2)(x-4)
• y=(x+1)²(x-3)(x-1)³
• y=(x+1)³(x-3)(x-1)²

Which of the following is a 5th degree trinomial with a leading coefficient of -2? 

• -2x⁵ + 3x - 1
• 5x^-2 +3x - 1
• -2x⁵ + 3x⁴ + 2x³ + x² - 10
• 2x + 5

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

What is the degree of the function graphed here?
Remember:  degree-1= number of extrema

• 2
• 3
• 4
• 5

Given the following factored form of a polynomial: 
f(x) = (x - a)(x - b)(x + c)(x + d)
The x-intercepts will be:

• x = a, b, -c, -d
• x = a, b, c, -d
• x = a, -b, -c, -d
• x = -a, b, -c, d

What is the equation in factored form of this graph?

• f(x) = (x-4)(x-1)²(x+2)(x+4)
• f(x) = (x-4)(x+1)²(x+2)(x+4)
• f(x) = (x-4)(x-1)²(x-2)(x+4)
• f(x) = (x+4)(x+1)²(x-2)(x-4)
