the domain and range of
For exponential function , there is no restriction for x
So domain is all real numbers
For exponential function ,
The range is y > b
The range of is y> -8
domain: {x | x is a real number}; range: {y | y > –8}

<u>Basic Finance Formulas </u>
One of the most-used formulas to compute present and future values is
Where FV is the future value, PV is the present value, r is the interest rate and n is the number of periods. It's vital to keep in mind that r and n must be referred to the same compounded time, e.g. r is compounded monthly and n is expressed in months
The question requires to compute the PV needed as a one-time deposit to earn a future value of $7,500 in 3 years at a 1.5% rate compounded monthly.
FV=7,500
r=1.5%=0.015
n=3*12=36 months
We converted n to months because r is compounded monthly . The formula
must be managed to make PV isolated
