Answer:
Interest earned= $200
Step-by-step explanation:
Giving the following information:
Initial investment= $20,000
Interest rate= 3%
Inflation rate= 2%
First, we need to calculate the real interest rate. <u>The inflation rate decreases the value of money through time. We need to deduct from the interest rate, the inflation rate.</u>
Real interest rate= 0.03 - 0.02= 0.01
<u>Now, we can calculate the interest earned in year 1:</u>
Interest earned= PV*(1+i)^n - PV
Interest earned= 20,000*(1.01^1) - 20,000
Interest earned= $200
f(x) = x² + 4x - 1
y = x² + 4x - 1
y + 1 = x² + 4x - 1 + 1
y + 1 = x² + 4x
y + 1 + 4 = x² + 4x + 4
y + 5 = x² + 2x + 2x + 4
y + 5 = x(x) + x(2) + 2(x) + 2(2)
y + 5 = x(x + 2) + 2(x + 2)
y + 5 = (x + 2)(x + 2)
y + 5 = (x + 2)²
y + 5 - 5 = (x + 2)² - 5
y = (x + 2)² - 5
f(x) = (x + 2)² - 5
