(2x³ + 5x² + 9) ÷ (x + 3)

(Remember place holders)

• 2x² - x + 3
• 2x³ - x² + 3x
• 2x² + 11x + 33 + 108/x+3
• 2x² - 5x + 12

Use synthetic division:
(2x³ - 5x - 7) ÷ (x - 2)

• 2x³ - 4x² + 3x - 13
• 2x³ + 4x² +3x - 1
• 2x² - 4x + 3 - 13/x-2
• 2x² + 4x + 3 - 1/x-2

 Identify whether the function graphed has an odd or even degree and a positive or negative leading coefficient.

• 1. The degree is odd, and the leading coefficient is negative.

• 1. The degree is even, and the leading coefficient is negative.

• 1. The degree is even, and the leading coefficient is positive.

• 1. The degree is odd, and the leading coefficient is positive

A graph is shown on the coordinate plane. Which function does the graph represent?

• f(x) = (x + 7)(x + 2)(x - 2)

• f(x) = (x +7)(x + 2)(x - 2)²

• f(x) = -(x +7)(x + 2)(x - 2)

• f(x) = - (x+7)(x+2)(x-2)²
