$x$ | $f(x)$ |
---|---|

$0$ | $8$ |

$1$ | $2$ |

$2$ | $0$ |

$3$ | $2$ |

$4$ | $8$ |

Recall that the highest or lowest point of a parabola is its vertex, which is on the axis of symmetry. Keeping this in mind, let's label the vertex.

We can see above that the vertex is the point $(2,0).$ Since the parabola opens *upwards,* the vertex is a minimum point.
