Question
Transcribed Image Text:There are many ways of applying exponential functions in our lives. Examples of
these are population growth, bacterial growth, radioactive decay, medical dosage,
and compound interest. An example of its application can be seen below.
Field of Application: Compound Interest
Situation analysis: Ms. Gomez decided to have an initial deposit to CDO Bank worth
P5,000.00 to save for future use. This decision came after an agent of the bank told
her that the bank is offering a 5% interest compounded annually. How much would
be Ms. Morales' total money in the bank after 5 years?
A(t) = P(1+ r)'
Use the given formula to find the total amount of money after 5 years.
Data manipulation: when t=0, A(0) = P(1 +.05)° = 5000
Presentation: Using a table of values, we have:

it has an increasing function. Thus, the values
increase at certain period of time. It is an
exponential growth. Ms. Gomez' money earned
P1,181.14 after 5 years in the bank. What

Now, It's Your Turn
1. Create your own or similar real-life situation where exponential function is
applied.
2. In a bond paper, present the problem from Field of application up to
Presentation as illustrated above.
3. You can use graphing paper, MS Excel, Desmos or any graphing app to graph
the function. You can also use calculators to solve the table of values.
4. Your grade will be according to these criteria: Clarity of Presentation 60%,
Organization and Accuracy, 30%, and Applicability to Current Situations,
10% with a total of 100%.
