Does this table represent a function? why or why not? x: 2 3 3 4 5 y: 1 4 3 2 5
gayaneshka [121]
Let's put the chart into ordered pairs:
(x, y)
(2,1)
(3,4)
(3,3)
(4,2)
(5,5)

In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function. 

The answer options may be mis-written. 
The answer is no, because one x value corresponds to more than one y-value.
