Term | Definition |
---|---|
exponential function | a function whose value is a constant raised to the power of the argument, with the parent function of f(x) = a times b^x Initial value, a: starting value when x=0 Base, b: growth rate; can be a percentage or factor |
exponential growth | growth whose rate becomes ever more rapid in proportion to the growing total number or size; occurs when b>1 growth factor, b growth rate, b -1: used with percentages |
exponential decay | growth whose rate becomes ever more rapid in proportion to the growing total number or size; occurs when b>1 Decay factor, b Decay factor, 1-b: used with percentages |
natural base,e | Euler's number, equivalent to approximately 2.7182818 |
transformations | the movement or shift in shape of a function |
domain | the set of all possible input values for the function |
range | all the output vales of a function |
interval of continuity | a function defined at every point on the interval |
interval of increasing | as the inputs increase, the outputs increase on the interval |
interval of decreasing | as the inputs increase, the outputs decrease on the interval |
horizontal asymptote | a horizontal line that a function approaches but never touches; equation, y= |
vertical asymptote | a vertical line that a function approaches but never touches; equation of x= |
end behavior | the value a function approaches as "x" approaches positive or negative infinity |
limit notation | the use of symbols to represent the value a function approaches. |
