Answer the following:

1.) Tom has started to collected game cards for 12 months. His monthly collection can be mapped by the function G = -t⁴ +13t³ -43t² +13t+48 where G is the number of game cards and t is the number of months since he started the collection. During which months did TOM collect 90 game cards?

a. 5 and 6
b. 7 and 8
c. 9 and 10
d. 6 and 7

2.) A demographer predicts that the population, P, of a town T years from now can be modelled by the function P(t)=6t⁴ -5t³ +200t+ 12 000. What will the population of the town be two(2) years from now?

a. 12 456
b. 124 560
c. 1 245 6000
d. 12 456 000

b. 3x³ + 2x² + 3x - 4

c. 27x^5 + 2x² + 3x - 4

d. 27x^5 - 2x² + 3x - 4

4.) Find the third degree polynomial functions with zeroes 3, -4, and 1/2.

a. P(x)= 2x³ + x² -25x + 12

b. P(x)= 2x³ + 2x² - 25x - 12

c. P(x)= x³ + 2x² - 25x + 12

d. P(x)= x³ + 3x² + 25x - 1
