the exponential function f(x) =
he invest $1000 for 5, 10, 15 years
5 years,
To find the amount of money he have , we plug in 5 for x and find out f(5)
f(x) =
f(5) = = 1762.34
The amount of money he have after 5 years is 1762.34
10 years,
To find the amount of money he have , we plug in 10 for x and find out f(10)
f(10) = = 3105.85
The amount of money he have after 10 years is 3105.85
15 years,
To find the amount of money he have , we plug in 15 for x and find out f(15)
f(15) = = 5473.57
The amount of money he have after 15 years is 5473.57
f(5) = 1762.34
f(10) = 3105.85
f(15) = 5473.57
S (ABCD) = S (ABC) + S (ADC)
