Answer:

1 - D

2 - C

3 - B

Step-by-step explanation:

To be a function an x value must only have one corresponding y value

Answer:

1) graph d

2) table c

3) coordinate points b

Step-by-step explanation:

1) the vertical line test is the  best way to insure whether or not a graph is a function. All the other graphs pasS the vertical line test but graph d does not, hence graph d is not a function.

2) to determine whether the table is a function or not you need to look at the "x" values. If there is a repeated number in the x  values, the table does not represent a function. Table c is the only one that represents a function.

3) coordinate points b are the only ones without a repetition of x coordinate points. Hope this helps!
