• INVERSE FUNCTION

  A relation reversing the process performed by any function f(x) is called inverse or f--1(x). This means that the domain of the inverse is the range of the original function and that the range of the inverse is the domain of the original function.
• Steps in solving inverse function:

  I. Let y = f(x).

  2. Interchange variable x and y.

  3. Solve for y in terms of x.

  4. Replace y by f−1(x).
• Lender or Creditor

  A person or institution who

  invests the money or makes the

  funds available.
• Borrower or Debtor

  A person or institution who owes

  the money or avails of the funds

  from the lender
• Origin or Loan Date

  Date on which money is received

  by the borrower
• Repayment Date or Maturity Date

  Date on which the money

  borrowed or loan is to be

  completely repaid
• Time or term (t)

  Amount of time in years the

  money is borrowed or invested,

  length of time between the

  origin and maturity date
• Principal (P)

  Amount of money borrowed or

  invested on the origin date
• Rate (r)

  Annual rate, usually in percent,

  charged by the lender, or rate of

  increase of the investment
• Interest (I)

  Amount paid or earned for the

  use of money
• Simple Interest (Is)

  Interest that is computed on the

  principal and then added to it
• Maturity value or future value (F)

  amount after t years; that the

  lender receives from the

  borrower on the maturity date

  
• COMPOUND INTEREST

  -the interest you earn on interest.
• COMPOUND INTEREST

  When the interest due at the end of a certain

  period is added to the principal and that sum earns

  interest for the next period, the interest paid is

  called compound interest.

  Ic = F − P
• COMPOUND INTEREST

  Future Value – the sum of principal

  amount and interest.

  Present Value – the principal amount.
• $F =$$P(1 + R)^T$

  A) COMPOUND INTEREST

  
• a

  A) A/F= P( 1 + R/2)^2T

  
• I

  A) A/F= P( 1 + R/4)^4T

  
• I

  A) A/F = P(1+r/k)^Kt,

• FV= P(1+RT)

  It is the other formula for Future Value.
• Power

  It is the process where it is multiplied by itself depending on the degree of the base.
• N(100)

  The formula to get the percentage is ?
• Rate

  It is usually in percent, charged by the lender.
• Exponential Equations

  It is an equation involving exponential expressions.
• Exponential Expressions

  It is an exponential involving expression.
• I = PRT

  The formula for Simple Interest is
• Law of Exponents

  It is a rule used to find the value of exponent.
• 1

  Solve 3560^0 =
• Compound Interest

  It is the difference of future value and principal.
