How do you find an explicit formula?

Match each polynomial function with one of its factors. 1. f (x) = x3 - 3x2 - 13x + 15 2. f (x) = x4 + 3x3 - 8x2 + 5x - 25 3. f (x) = x3 - 2x2 - x + 2 4. f (x) = - x3 + 13x - 12 Pairs 1. x - 2 2. x + 3 3. x + 4 4. x + 5

Tell whether each equation represents a direct variation. if so, identify the constant of variation. 1. y=4x+9 2. 2y=-8x 3. x+y=0
