Inverse function:

The only one that has an inverse that is a function is the third option because is a linear function (bijective)

y=1/3x-3/4

First, solve for x:

Add 3/4 to both sides:

y+3/4 = 1/3x-3/4+3/4

y+3/4 = 1/3x

Multiply both sides by 3

(y+3/4) 3 = 1/3x (3)

3y+ 9/4 = x

F^-1(y) = 3y+ 9/4

An investment of $7,650 at the rate of 5% and is compounded quarterly. What is the investment at the end of 9 years?
ankoles [38]

Answer:

FV = P(1 + r/t)^nt; where P is the initial investment, r is the rate, t is the number of accumulation in a year, n is the number of years.

FV = 7650(1 + 0.05/4)^(9 x 4) = 7650(1 + 0.0125)^36 = 7650(1.0125)^36 = 7650(1.564) = $11,964.17
