Answer:
A
Step-by-step explanation:
Given the exponential function
f(t) = 228
← where t is time in years
Substitute t = 20 into f(t), that is
f(20) = 228 × 
= 228 × 0.60268.... ≈ 137 → A
The answer to this is y=5
Since it's 8% every year, we have 8% of 600 equals 8*6=48. 48/365 is the amount of interest per day, and 48*45/365 is what you would get over 45 days, which is approximately 5.9 dollars
Note that this is assuming interest is compounded every year
The mathematical term meaning " a parabola highest point " is the Vertex.
