![### Problem 4: Understanding Exponential Decay
What if we started with the house having a size of 1.5 ft.? If a click to go smaller reduces the size by 50%, what formula could we use that is well connected to the first one?
Given formula:
\[ f(x) = a(c)^x \]
Where:
- \( a \) is the initial size of the house.
- \( c \) is the reduction factor.
- \( x \) represents the number of clicks.
Based on the problem:
- \( a \) is ________ and its value is \( a = 1.5 \) ft.
- \( c \) is ________ and its value is \( c = 0.5 \) (since the size reduces by 50% each click).
- \( x \) represents ________ the number of clicks.
This formula helps us understand how the size of the house changes exponentially with each click.
**Note:** This problem involves understanding how exponential decay works, which is a crucial concept in mathematics, especially in contexts such as population decline, radioactive decay, and in this case, size reduction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71e9498b-aba9-407d-bec7-742f7e9d7c6e%2F2f7a463c-f86f-4366-9557-da2f7942591d%2Fh38pzmf_processed.jpeg&w=3840&q=75)

![### Stock Growth and Decline Formulas
#### 5. Stock Growth Formula
If you own one share of stock in GameStop that was worth $100 when you bought it, what formula would show it having 4% growth a year?
The formula given is:
\[ f(x) = a(c)^x \]
To understand the components of this formula:
- **a** is __________________ and its value is \( a = \) _______
- **c** is __________________ and its value is \( c = \) _______
- **x** represents __________________
#### 6. Stock Decline Formula
What if your hundred dollars share instead lost 4% per year? What does this formula look like?
The formula remains similar:
\[ f(x) = a(c)^x \]
We need to define the components for the decline scenario:
- **a** is __________________ and its value is \( a = \) _______
- **c** is __________________ and its value is \( c = \) _______
- **x** represents __________________
### Biological Half-Life of Medication
#### 7. Over-the-Counter Headache Reliever
The biological half-life of an over-the-counter headache reliever is 1 hour. This means that the amount of pain reliever in the body is reduced by 50% every hour. Suppose Jasper took 200 mg of this medication. Write a function \( f \) that you can use to model t hours after taking the medication.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71e9498b-aba9-407d-bec7-742f7e9d7c6e%2F2f7a463c-f86f-4366-9557-da2f7942591d%2Fwllgf6cg_processed.jpeg&w=3840&q=75)
