4.  Function: a relation that assigns exactly one output value for each input value.

6. Determine whether the relation is a function. {(–4, 0), (2, 12), (–1, –3), (1, 5)} The relation is a function.

7. Determine whether the relation is a function. {(4, 3), (2, –1), (–3, –3), (2, 4)} The relation is not a function.

8. Use a mapping diagram to determine whether the relation is a function

10. The vertical-line test says that, on a graph, If any vertical line passes through more than one point of the graph, then the relation is not a function. http://www.phschool.com/atschool/acade my123/english/academy123_content/wl- book-demo/ph-188s.html

11.  No  No vertical line passes through more than one point. is  The relation is a function. {(0,-2),(1,-2),(-3,1),(-2,0), (-1,-1),(3,2),(2,-3)}

12. is  The relation is a function.
