Coefficient |
A coefficient is the number in front of a variable. |

Dilation |
To reduce or enlarge a figure according to a scale factor is a dilation. |

domain |
The domain of a function is the set of -values for which the function is defined. |

Horizontal shift |
A horizontal shift is the result of adding a constant term to the function inside the parentheses. A positive term results in a shift to the left and a negative term in a shift to the right. |

Parabola |
A parabola is the characteristic shape of a quadratic function graph, resembling a "U". |

quadratic function |
A quadratic function is a function that can be written in the form , where , , and are real constants and . |

standard form |
The standard form of a quadratic function is . |

Symmetry |
A figure has symmetry if it can be transformed and still look the same. |

Vertex |
The vertex of a parabola is the highest or lowest point on the graph of a parabola. The vertex is the maximum point of a parabola that opens downward and the minimum point of a parabola that opens upward. |

vertical axis |
The vertical axis is also referred to as the -axis of a coordinate graph. By convention, we graph the output variable on the -axis. |
