Term | Definition |
---|---|
Square Root | If b^2 = a, then b is a square root of a. The radical sign, V-, represents a nonnegative square root. |
Radical Sign | The symbol V- which is used to represent a square root |
Radicand | The number or expression under a radical sign |
Square Root Equation | An equation that contains a square root with a variable in the radicand |
Closed | A set of numbers is closed under an operation when the operation performed on any two numbers in the set results in a number that is also in the set |
nth root | When b^n = a for an integer n greater that 1,b is an nth root of a |
Exponential Function | A function of the form y =ab^x, where a =/ 0, b=/ 1, and b > 0 |
Exponential Growth | When a quantity increases by the same factor over equal intervals of time |
Exponential Growth Function | A function of the form y = a(1 + r)^t, where a > 0 and r > 0 |
Compound Interest | Interest earned on the principal and on previously earned interest |
Exponential Decay | When a quantity decreases by the same factor over equal intervals of time |
Exponential Decay Function | A function of the form y = a(1 - r)^t |
Geometric Sequence | A sequence in which the ratio between consecutive terms is the same; This ratio is called the common ratio |
Common Ratio | The ratio between consecutive terms of a geometric sequence |
Recursive Rule | Gives the beginning term(s) of a sequence and an equation that indicates how any term aVn in the sequence relates to the previous term. |
