## Parent Functions and Their Graphs

Parent functions are the basic functions that form the foundation for more complex functions. They have simple equations and distinct graphs that serve as building blocks for transformations and other operations.

Common parent functions include:

Function | Equation | Graph |
---|---|---|

Constant function | f(x) = c | Horizontal line at y = c |

Linear function | f(x) = mx + b | Straight line with slope m and y-intercept b |

Quadratic function | f(x) = ax^{2} + bx + c |
Parabola opening up (a > 0) or down (a < 0) |

Absolute value function | f(x) = |x| | V-shaped graph with a vertex at the origin |

Square root function | f(x) = √x | Right half of a parabola opening up |

Exponential function | f(x) = a^{x} |
Exponential curve increasing (a > 1) or decreasing (0 < a < 1) |

Logarithmic function | f(x) = log_{a}(x) |
Inverse of the exponential function |

## Transformations of Parent Functions: Parent Functions Graphic Organizer Answer Key

Transformations are operations that can be applied to parent functions to create new functions with different graphs. Common transformations include:

Transformation | Effect on Graph |
---|---|

Vertical shift | Moves the graph up (positive shift) or down (negative shift) |

Horizontal shift | Moves the graph to the right (positive shift) or left (negative shift) |

Vertical stretch | Stretches the graph vertically by a factor of |a| |

Vertical shrink | Shrinks the graph vertically by a factor of |a| |

Horizontal stretch | Stretches the graph horizontally by a factor of |a| |

Horizontal shrink | Shrinks the graph horizontally by a factor of |a| |

Reflection | Reflects the graph over the x-axis (y-reflection) or y-axis (x-reflection) |

## Identifying Parent Functions
