stan nct127 is 100% correct.
if ur unsure of the letters here are the answers:
1: exponential decay:4
2: exponential growth:12
3:exponential growth: 129
4:rick: $1,480; sally: $1,500
5: y=120,000(1.012)*;143,512
6:y=1,860,000(0.985) ; 1,551,485
7: 2,249.73
8: 4,051.63
10: 6 years
HAPPY HOLIDAYS EVERYONE<3

stan is 100% correct. thx
Oh and the quick check!
1. A) (You can double check on desmos or mathway)
2. B) 130% increase
3. D) f(x)= 175 (1.22)^x ; 473
4. C) 7 years
5. D) y= 110(0.9)^x
stan nct127 has all the correct ones
Tea is correct for the quick check
Thank you<3
My answer is y intercept is 4.
Explanation:
In order to find the y intercept of a function, just let the value of x equals to 0.
5/6 raise to zero is equal to 1. ( rule: any number raise to 0 is equal to one)
So 4 times 1 equals to 4.
* It is an exponential decay..
Explanation:
Try substituting some values to x, for example:
4 times (5/6) raise to 1 is equal to 10/3 or 3.3333..
4 times (5/6) raise to 2 is equal to 25/9 or 2.77..
Just by doind that you can know if it is a growth or a decay.
Thxss. last day x_x
