F(5) = -4(25) - 3 = -100 -3 = -103
answer
f(5) = -103
g(-5) = 3(-5) - 1 = -15 -1 = -16
answer
g(-5) = -16
Answer:

Step-by-step explanation:
Set up the equation:
Since C(t) gives the number of cars purchased in the t-th year after 1998, then make the number of cars equal to 15 000 and solve for t - the year:
20t^2 = 15000
t^2 = 750
t = 
The year will be simply 1998 + 5 \sqrt{30}
