Answer:
Step-by-step explanation:
It's solved by grafic method
Answer:Yes, it is
2^2+4(2)-12=0
4+8-12=0
12-12=0
0=0
x= -1 y= -1
f(x) = Ca^x
x = years since 2000.
f(0) = 220000 = Ca^0 = C
f(x) = 220000a^x
f(1) = 220000(1-0.11) = 220000a^1
a = 0.89
f(x) = 220000(0.89)^x
So each year reduces by 89%
1. (0,5)
2. 3 / -1
3. F(x) = -3x + 5
