Which table shows a function that is decreasing only over the interval (–1, 1)?

the third function

Step-by-step explanation:

when looking at x=-1 the value goes from (x=-2) 0 to -3, when x=0 it goes to 0, and then only increases after that.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
