Which sequence is exponential and shows decay?
F 600, 480, 360, 240
G 440,220, 110, 55
H 25, 50, 100, 200
J100, 150, 200, 250
K 4, 18, 22, 26

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

a: 1/6, j: 1/4
