The table shows the number of llamas born on llama ranches worldwide since 1988. Find a cubic function to model the data and use it to estimate the number of births in 1999.
Years since 1988 1 3 5 7 9
Llamas born (in thousands) 1.6 20 79.2 203.2 416

a. L(x) = 8.1x^2 - 30.4x + 28.7; 741,600 llamas
b. L(x) = 0.5x^3 - 0.6x^2 + 0.3x + 0.2; 563,200 llamas
c. L(x) = 0.5x^3 + 0.6x^2 + 0.3x + 0.2; 741,600 llamas
d. L(x) = 8.1x^2 - 30.4x + 28.7; 563,200 llamas

Question

The table shows the number of llamas born on llama ranches worldwide since 1988. Find a cubic function to model the data and use it to estimate the number of births in 1999.
Years since 1988	1	3	5	7	9
Llamas born (in thousands)	1.6	20	79.2  203.2  416

a.	L(x) = 8.1x^2 - 30.4x + 28.7; 741,600 llamas
b.	 L(x) = 0.5x^3 - 0.6x^2 + 0.3x + 0.2; 563,200 llamas
c.	 L(x) = 0.5x^3 + 0.6x^2 + 0.3x + 0.2; 741,600 llamas
d.	L(x) = 8.1x^2 - 30.4x + 28.7; 563,200 llamas
