### STAAR Practice for Algebra 1 Vocabulary-Set 1

Term | Definition |
---|---|

Function | Every x has exactly 1 y value (x's don't repeat) |

Independent Variable | The variable that does not depend on something else, it can stand alone. (Words that represent the x values) |

Dependent Variable | Variable that depends on something else. (represents the y values) |

Equations | A math sentence stating 2 expressions are equal. (Does have an = sign) |

Inequality | A statement that uses the symbols <, >, <=, >= |

Parent Function Linear and Quadratic | Linear is y = x Quadratic is y = x^2 |

Domain | the of x values |

Range | the y values |

Correlation | A relationship between two sets of data (Positive, Negative, No Correlation) |

Variable | A letter or symbol that represents an unknown number |

y-intercept | Where a graphed line or curve crosses the y axis |

x-intercept | Where a graphed line or curve crosses the x axis |

Parallel Lines | Two lines that never cross. (Have the same slope) |

Slope | The rate of change. (The steepness of a line) |

Direct Variation | Linear function in the form of y=kx. (It is proportional) |

Base | The number or symbol being multiplied (has an exponent) |

Exponent | A small superscript number that shows how many times a base is to be multiplied. |

Zeros/Roots | The x-intercept. (Zeroes are written (#, 0) and roots are written as x=#) |

Minimum | The bottom point where the graph changes directions. (the vertex of the quadratic with a positive value of a) |

Maximum | The high point where the graph changes directions. (the vertex of the quadratic with a negative value of a) |
