two students are working on the same problem:
a juice box has 20% more juice in its new packaging. the original packaging held 12
fluid ounces. how much juice does the new packaging hold?
• here is how priya set up her double number line.
12 14.4
juice (fluid ounces) +
100%
120%
140%
0% 20% 40% 60% 80%
here is how clare set up her double number line.
12
juice (fluid ounces)
15
0%
20%
40%
60%
80%
100%
120%
40%
do you agree with either of them? explain or show your reasoning.

We need to find the function that represents the exponential decay.

We are given options:

f(x) = 0.6(2)^x

f(x) = 3(0.7)^x

f(x) = 0.4(1.6)^x

f(x) = 20(3)^x.

Standard form of an exponential function is .

Where a is the initial value and b is the growth or decay factor.

If value of b is less than 1 then it would be an exponential decay.

In the second option we are given f(x) = 3(0.7)^x, the value of b is 0.7.

That is less than 1.

Therefore,  f(x) = 3(0.7)^x function shows exponential decay.
