The required function is:
Option 3: [tex]f(t) = 37. (1.05)^t[/tex]
Step-by-step explanation:
The initial value and rate is used to write exponential function
Here
Given
Initial value = 37
Rate = r = 5%
When the rate is 5%, the next year the quantity will be 1+0.05 = 1.05 time of the current quantity.
So,
The function can be written as:
[tex]f(t) = 37. (1.05)^t[/tex]
For initial value, put t=0
[tex]f(t) = 37. (1.05)^0\\f(t) = 37 * 1\\f(t) = 37[/tex]
Hence,
The required function is:
Option 3: [tex]f(t) = 37. (1.05)^t[/tex]
