Step: 1

Draw the mapping diagram for the given relation.

Step: 2

A relation is a function if each element in the domain is paired with one and only one element in the range.

Step: 3

From the mapping diagram, it can be observed that the given relation is a function.

Correct Answer is : Figure 1, Relation is a function

Input | Output |

- 5 | - 9 |

- 6 | - 11 |

- 5 | - 13 |

- 8 | - 15 |

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

The relation given is not a function because the input - 5 has two outputs - 9 and - 13.

Correct Answer is : it is not a function

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

The relation is not a function because the input 2 has three outputs: - 4, 5 and - 6.

Correct Answer is : It is not a function

Step: 1

In the relation, for each input there is exactly one output.

Step: 2

The relation is a function.

Step: 3

The domain of the function is 1, 3, and 5.

Step: 4

The range of the function is 6, 2, and 10.

Correct Answer is : it is a function; domain is 1, 3, 5 and range is 6, 2, 10

Step: 1

The relation is a function, if there is exactly one output for every input.

Step: 2

In the given relation 22 has two outputs - 24 and - 25.

Step: 3

So, the relation represented in the set of ordered pairs is not a function.

Correct Answer is : It is not a function.

Step: 1

The given ordered pairs are: {(6, 64), (7, 94), (5, 54)}

Step: 2

A relation is a function if each input corresponds to one and only one output.

Step: 3

So, the given relation is a function.

Correct Answer is : It is a function.

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

In the plot, for each x -coordinate, there is only one y -coordinate.

Step: 3

So, the relation is a function.

Step: 4

The domain is 1, 2, 3, and 6 and the range is 2, 3, 4, and 6.

Correct Answer is : It is a function, domain: 1, 2, 3, and 6; range: 2, 3, 4, and 6.

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

For each input 2, 3, 5, and 7, there is exactly one output.

Step: 3

So, the relation is a function.

Step: 4

Range is 11, 13, 17, and 19.

Correct Answer is : It is a function; range is 11, 13, 17, 19.

Step: 1

In the relation, for each input there is exactly one output.

Step: 2

The relation is a function.

Step: 3

The domain of the function is {1, 3, 5}.

Step: 4

The range of the function is {6, 2, 10}.

Correct Answer is : It is a function; domain is {1, 3, 5} and range is {6, 2, 10}.

Input | Output |

- 4 | - 7 |

- 5 | - 9 |

- 4 | - 11 |

- 7 | - 13 |

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

The relation given is not a function because the input - 4 has two outputs - 7 and - 11.

Correct Answer is : It is not a function.

Step: 1

A relation is a function if for every input there is exactly one output.

Step: 2

The relation given is not a function because the input 2 has two outputs - 1 and 3.

Correct Answer is : It is not a function.

Step: 1

A relation is a function if every input has exactly one output.

Step: 2

The relation is not a function because the input 5 has three outputs: - 7, 8, and - 9.

Correct Answer is : It is not a function

Step: 1

Draw the mapping diagram for the given relation.

Step: 2

A relation is a function if each element in the domain is paired with one and only one element in the range.

Step: 3

From the mapping diagram, it can be observed that the given relation is a function.

Correct Answer is : Figure 1, Relation is a function

Input | Output |

5 | 7 |

6 | 8 |

7 | 9 |

8 | 10 |

Step: 1

For each input there is exactly one output.

Step: 2

So, the relation is a function.

Step: 3

The domain is 5, 6, 7 and 8. The range is 7, 8, 9 and 10.

Correct Answer is : It is a function, domain: 5, 6, 7 and 8 range: 7, 8, 9 and 10
