## Section 1

Question | Answer |
---|---|

what does it mean if "a" is greater than 1 ? | we have Exponential Growth |

what does it mean if "a" is less than 1 ? | we have Exponential Decay |

what is the largest possible domain for the Exponential Function? | All Real Numbers |

what are exponential growth / exponential decay often described in? | in terms of Percent(%) growth / decay |

what is the general formula for Exponential Functions? | P = Po(a)^t |

how do we find "a" ? | a = 1 + r |

Linear Function changes by a fixed ....? | number |

Exponential Function changes by a fixed...? | percentage(%) |

If a question ever says "leaving the body" what does that mean? | that it is Exponential Decay |

How can we tell if data from a table..came from an Exponential Function? | step1: look at the number column on the right side of the table 2: take each number and DIVIDE it by the previous number 3: After Dividing all of them...if they are all EQUAL...then it came from an Exponential Function |
