1)

The function represents a domain and range of the points.

SInce,the -values for the domain and the -values for the range.

For a relation to be a function, each -value has to go to one, and only one,-value.

The set of points are

Option 1 is correct answer.

3)

Observe the graph,

The line represents the solid line and above the -axis at .

The function represents symbol of
