| exponential function | a function of the form y=ab^x where b > o and not equal to 1 |
| scientific notation | a number expressed in the form c times 10^n where 1 is greater than or equal to c and < 10 and n is an integer |
| exponential growth | a quantity that is increasing by the same percent in each unit of time (t) where C is the initial amount |
| growth factor | the expression 1 + r in the exponential growth model where r is the growth rate |
| initial amount | the variable C in the exponential growth or decay model |
| time period | the variable t is the exponential growth and decay models |
| percent of increase | the expression 100r is the percent of increase where r is the growth rate in the exponential growth model |
| growth rate | the variable r in the exponential growth model |
| exponential decay | a quantity that is decreasing by the same percent in each unit of time t where c is the initial amount |
| decay factor | an expression 1-r in the exponential decay model where r is the decay rate |
| decay rate | the variable r in the exponential decay model |
| percent of decrease | the expression 100r is the percent of decrease where r is the decay rate in the exponential decay model |
