The parent function of

is

The diagrams below show step by step transformation
As we can see from the graph

, the amplitude of the function is 3, period of

, phase shift of π and midline y=2
Given:
Amount after three years = $10000
Rate of interest = 8.2 percent compounded monthly = 0.082
Time = 3 years
To find:
The principal value.
Solution:
Formula for amount is

where, P is principal, r is rate of interest, n is the number of times interest compounded in an year, t is number of years.
Substitute A=10000, r=0.082, n=12 and t=3 in the above formula.




Divide both sides by 1.27783.
