a) f (2) = 1
b)
c)
<u>Step-by-step explanation:</u>
- Indicates that we have to find the inverse of the function
Given data:
--------> eq.1
---------> eq.2
To find
Case a)
Now, substitute x = 2 in the equation 1 to find f (2)
Case b)
Now, substitute x = 1 in the equation 2 to find
Case c)
In general,
Thereby,
The exponential function that approximates the amount of money in her account using a weekly growth rate is:
What is an exponential function?
An increasing exponential function is modeled by:
In which:
In this problem, the yearly function is:
Considering that a year has 52 weeks, we have that:
0.06/52 = 0.001154
Hence:
