In a relation, the set of first numbers of the ordered pairs. | domain |

It represents the horizontal placement of a point on a coordinate graph. | x-coordinate |

Used to determine if a graph represents a function. | vertical line test |

Finding the value for a variable that makes a mathematical sentence true. | solving |

An expression like x^n where x is the base and n is an exponent. | power |

The rule that lets you know which operation to perform first when evaluating an expression. | order of operations |

Each object or number in the replacement set. | element |

In a relation, the variable with a value that is dependent on the value of the independent variable. | dependent variable |

A function with a graph that is not a straight line. | nonlinear function |

Letters or symbols used to represent unspecified numbers or values. | variables |

Indicates the number of times the base is used as a factor. | exponent |

In a relation, the set of second numbers of the ordered pairs. | range |

Two numbers whose product is one. It is the same as reciprocals. | multiplicative inverses |

A set of ordered pairs. | relation |

The vertical number line in a coordinate plane. | y-axis |

The point where the x-axis and y-axis intersect. | origin |

A function graphed with a line or smooth curve. | continuous function |

Expressions that represent the same value. | equivalent expressions |

A set of numbers from which replacements for a variable may be chosen. | replacement set |

Consists of sums and/or products of numbers and variables. | algebraic expressions |

A mathematical statement that contains algebraic expressions and symbols. | open sentence |

The product of 1 and a number is equal to the number. | multiplicative identity |

It represents the vertical placement of a point on a coordinate graph. | y-coordinate |

In a power it is the number being multiplied repeatedly as a factor. | base |

In a relation, the variable whose value determines the output. | independent variable |

An expression that contains no like terms or parentheses. | simplest form |

A collection of objects or numbers that is often shown using braces. | set |

To find the value of an expression. | evaluate |

The horizontal number line in a coordinate plane. | x-axis |

The sum of any number and 0 is equal to the number. | additive identity |

The plane formed by the x-axis and the y-axis. | coordinate plane |
