Graph the system of inequalities. Solution:

Step 1: |
---|

First we replace the inequalities with equality. So , and . |

Now we graph both functions. |

Step 2: |
---|

Now that we have graphed both functions we need to know which region to shade with respect to each graph. |

To do this we pick a point an equation and a point not on the graph of that equation. We then check if the |

point satisfies the inequality or not. For both equations we will pick the origin. |

Plugging in the origin we get, . Since the inequality is false, we shade the side of |

that does not include the origin. We make the graph of dashed, since the inequality is strict. |

Plugging in the origin we get . Since this inequality is true, we shade the side of that includes the origin. Here we make the graph of solid since the inequality sign is |

Final Answer: |
---|

The final solution is the portion of the graph that below and above |

The region we are referring to is shaded both blue and red. |
