Answer:
Bottom right
Step-by-step explanation:
For a set of numbers to be function the independent variable must have only one value in the dependent variable.
You can do it with graphs or tables.
Here you can analyze each graph.
Top Left:
for x = -1, y = -1 and also y = 3, then it isnt a function because there are 2 values in y for 1 value in x
Top Right:
for x = 0, y = -1 and also y = 2, it isnt a function
Bottom Left:
for x = -2, y= -2 and also = 1, for x = 2, y = -2 and also y = 0, it isnt a function
Bottom right:
Each x has only 1 y. It is a function
