1. Function: Yes

Domain: {-5, 0, 7}

Range: {2, 5, 9}

2. A graph with points plotted that do not pass the vertical line test, indicating it is not a function.

3. Function: Yes

Domain: {-5, -2, 0, 3, 5}

Range: {-6, -4, 0, 5, 12}

4. A graph of a straight line that passes the vertical line test, indicating it is a function.

5. Function: No (because the x-value 3 corresponds to two different y-values)

6. A mapping diagram with x-values having multiple y-values, indicating it is not a function.

The image contains a worksheet with six problems, each asking to determine whether a given graph, list, mapping, or table represents a function, and if so, to state the domain and range. Here are the details for each problem:

1. A table with three pairs of x and y values:

- (-5, 2)

- (0, 5)

- (7, 9)

Function: Yes

Domain: {-5, 0, 7}

Range: {2, 5, 9}

2. A graph with points plotted that do not pass the vertical line test, indicating it is not a function.

3. A mapping diagram with unique x-values all having a single y-value:

- (-5, -6)

- (-2, -4)

- (0, 0)

- (3, 5)

- (5, 12)

Function: Yes

Domain: {-5, -2, 0, 3, 5}

Range: {-6, -4, 0, 5, 12}

4. A graph of a straight line that passes the vertical line test, indicating it is a function.

5. A table with four pairs of x and y values:

- (-2, -4)

- (3, 0)

- (3, 4)

- (5, 11)

Function: No (because the x-value 3 corresponds to two different y-values)

6. A mapping diagram with x-values having multiple y-values, indicating it is not a function.

For the graphs that are functions (1, 3, and 4), the domain and range can be determined by the x and y values that are included in the function. For the graphs that are not functions (2, 5, and 6), the domain and range are not applicable in the context of a function. The exact domain and range for graph 4 would need to be determined by analyzing the graph further.
