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

Average Rate of Change | The change in the value of a quantity by the elapsed time. For a function, this is the change in the y |

Constant Rate of Change | With respect to the variable x of a linear function y = f(x), the constant rate of change is the slope of its graph. |

Continuous | Describes a connected set of numbers, such as an interval |

Discrete | A set with elements that are disconnected. |

Domain | The set of x |

End Behaviors | The appearance of a graph as it is followed farther and farther in either direction. |

Explicit Expression | A formula that allows direct computation of any term for a sequence a1, a2, a3, . . . , an, . . |

Exponential Function | A nonlinear function in which the independent value is an exponent in the function, as in y = abx. |

Exponential Model | An exponential function representing real |

Expression | Any mathematical calculation or formula combining numbers and/or variables using sums, differences, products, quotients including fractions, exponents, roots, logarithms, functions, or other mathematical operations. |

Even Function | A function with a graph that is symmetric with respect to the y |

Geometric Sequence | A sequence of numbers in which the ratio between any two consecutive terms is the same. In other words, you multiply by the same number each time to get the next term in the sequence. This fixed number is called the common ratio for the sequence. |

Interval Notation | A notation representing an interval as a pair of numbers. The numbers are the endpoints of the interval. Parentheses and/or brackets are used to show whether the endpoints are excluded or included. |

Linear Function | A function with a constant rate of change and a straight line graph. |

Linear Model | A linear function representing real |

Odd Function | A function with a graph that is symmetric with respect to the origin. A function is odd if and only if f(–x) = –f(x). |

Parameter | The independent variable or variables in a system of equations with more than one dependent variable. |

Range | The set of all possible outputs of a function |

Recursive Formula | A formula that requires the computation of all previous terms to find the value of an. |

Slope | The ratio of the vertical and horizontal changes between two points on a surface or a line. |

Term | A value in a sequence |

Vertical Translation | A shift in which a plane figure moves vertically. |

x-intercept | The point where a line meets or crosses the x-axis |

y-intercept | The point where a line meets or crosses the y-axis |
