So just plug in the 4 wherever you see an x. so it is f(4)=2(4)
Answer:
A = $4652.37
Step-by-step explanation:
Given:
Initial amount (P) = $4000
Interest rate (r) = 5.1 %
n = 2 (Compounding per year)
t = 3 years
Using Compound interest formula:
![A =P(1+ r/n )^(nt)\\\\A = 4000( 1 + (0.051/2))^(2*3)\\A = $4652.37](https://tex.z-dn.net/?f=A%20%3DP%281%2B%20r%2Fn%20%29%5E%28nt%29%5C%5C%5C%5CA%20%3D%204000%28%201%20%2B%20%280.051%2F2%29%29%5E%282%2A3%29%5C%5CA%20%3D%20%244652.37)
