The annual number of cars and trucks sold by a dealership can be modeled by the functions
given below where x is the number of years since 2000.
Fi
Cars sold: c(x) =1.118x³ – 22.1492x +95.2693x +1210.7673
Trucks sold: t(x)=1.5964x³ - 36.4112x +200.5798x+476.9031
56. Write a function, T(x), that models the total annual number of cars and trucks sold.
A) T(x)=2.7144x³ – 58.5604x² +295.8491x +1687.6704
6.
B) T(x) =0.4784x³ –14.262x +105.3105x-733.8542
C) T(x) =2.7144x – 58.5604x² +105.3105x +733.7642
Cho
D) T(x)=-0.4784x° +14.262x² – 105.3105x +733.8642
A) {
57. Write a function, D(x), that models how many more cars than trucks were sold annually.
AB)
A) D(x)=2.7144x³ +58.5604x +295.8491x +1687.6704
B) D(x) =0.4784x' -14.262x? +105.3105x -733.8642
C) D(x)=2.7144x³ – 58.5604x² +105.3105x+733.7642
Fi
D) D(x)=-0.4784x³ +14.262x² – 105.3105x+733.8642
58. According to the model, how many cars and trucks were sold in 2009? (Round to nearest
whole number.)
