Makovka662 [10]
Let's say the APR is 5%. That means you get 5% of your balance back every year. The $100 balance would get $5 back, the $500 balance would get $25 back, and the $1000 balance would get $50 back. Therefore, all of the balances would take the same amount of time to double, and it would take all of them 20 years.

$5*20 years=$100
$25*20 years=$500
$50*20 years=$1000

Which function is graphed below?<br> y=j3)
natita [175]

Answer:

y = 3(\frac{1}{3} )^{x}

Step-by-step explanation:

See the attached graph.

The points (0,3) and (1,1) are on the graph of the exponential function.

Let the function be y = a(b)^{x} ....... (1)

Now, satisfying the point (0,3) we get from the equation (1),  

3 = a(b)^{0} = a

Therefore, the initial value of the function is a = 3

Hence, the equation becomes y = 3(b)^{x} ......... (2)

Now, satisfying the point (1,1) we get from equation (2)  

1 = 3 (b)^{1}

⇒ b = 1/3

So, the final equation becomes y = 3(\frac{1}{3} )^{x} (Answer)
