# A function from the set X={-1,0,1,2,3,4} to the set R is given by the followin table.

## Question:

A function from the set {eq}X=({-1, \ 0, \ 1, \ 2, \ 3, \ 4}) {/eq} to the set {eq}R{/eq} is given by the following table.

X | R |

-1 | 2 |

0 | 1 |

1 | 2 |

2 | 5 |

3 | 10 |

4 | 17 |

(a) Write the function f as a function of ordered pairs?

(b) Can you create an equation to describe the function {eq}f{/eq}?

## Functions:

The function in mathematics is a law or expression that is used to represent a physical relationship between the set of input values and the set of permissible outputs with the property that each input variable is related to exactly one output variable.
