Question

1.Create your own or similar real-life situation where exponential function is applied 2. In 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.

Answer 1

Solution:

1. Tim invested $5000 in a bank that pays an annual interest rate of 10% compounded continuously. What is the amount he can get after t years from the bank?

We can represent it as: $A=Pe^{rt}$

where $A=$ amount received after t years,

$P=\$ 5000 \\r=10\%=0.1$

So, $A=5000e^{0.1t}$

which is clearly an exponential function in real-life.

2. Using bond paper is a practical part, that can be done by performer only.

3. Its graphon desmos is:
